Machining Specifcations
O-Ring Gland Types
O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below
Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section
Selecting an O-Ring Cross-Section
Piston Configuration Rod Configuration
Face Type Configuration
bull More compactbull Lighter weightbull Less expensive especially for higher cost
elastomers like FKM or fluorosiliconebull Less machining required for machined grooves
since grooves are smallerbull More resistant to explosive decompression
bull Less prone to compression setbull Less volume swell in liquid on a percentage
basisbull Allows for larger tolerance while still
maintaining acceptable compression squeezeand compression ratio over full stack-up range
bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088
Rod Type sealExtrusion Gap = Bore 983088- Rod 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

O-Ring Gland Types
O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below
Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section
Selecting an O-Ring Cross-Section
Piston Configuration Rod Configuration
Face Type Configuration
bull More compactbull Lighter weightbull Less expensive especially for higher cost
elastomers like FKM or fluorosiliconebull Less machining required for machined grooves
since grooves are smallerbull More resistant to explosive decompression
bull Less prone to compression setbull Less volume swell in liquid on a percentage
basisbull Allows for larger tolerance while still
maintaining acceptable compression squeezeand compression ratio over full stack-up range
bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces
Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression
Suggested solutions Gland design should take into
account material responses to chemical and thermalenvironments
Over-Compression
Description The seal exhibits cuts or marks which spiralaround its circumference
Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness
elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication
Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings
Spiral Failure
Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered
Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing
Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings
Extrusion (andor Nibbling)
Common O-Ring Failures

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces
Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical
Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility
Compression Set
Description The seal or parts of the seal may exhibit smallcuts nicks or gashes
Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus
hardness elastomer Elastomer surface contamination
Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer
Installation Damage
Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size
Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer
Suggested Solutions Avoid plasticized elastomers Ensure
all seals are properly post-cured to minimize outgassing
OutgassingExtraction

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures
Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling
Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces
Thermal Degradation
Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed
Contributing Factors Rapid pressure changes Low-
modulus hardness elastomer
Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)
Explosive Decompression
Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable
only by measurement of physical properties
Contributing Factors Incompatibility with the chemicalandor thermal environment
Suggested Solutions Selection of more chemicallyresistant elastomer
Chemical Degradation

Description The seal or parts of the seal exhibit a flatsurface parallel to the direction or motion Loose particlesand scrapes may be found on the seal surface
Contributing Factors Rough sealing surfaces Excessivetemperature Process environment containing abrasiveparticles Dynamic motion Poor elastomer surface finish
Suggested Solutions Use recommended gland surfacefinishes Consider internally lubed elastomers Eliminateabrasive components
Abrasion
Description The seal often exhibits discolouration as wellas powdered residue on the surface and possible erosion ofelastomer in the exposed area
Contributing Factors Chemical reactivity of the plasmaIon bombardment (sputtering) Electron bombardment(heating) Improper gland design Incompatible sealmaterial
Suggested Solutions Plasma-compatible elastomer andcompound Minimize exposed area Examine gland design
Plasma Degradation
Description The seal exhibits foreign materials on thesurface andor within the O-ring
Contributing Factors Process environment depositionReactions or degradation of the elastomer Non-semiconductor-grade elastomer
Suggested Solutions Specify contamination levelincluding manufacturing and packaging of the seals

O-Ring Gland Types
O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below
Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section
Selecting an O-Ring Cross-Section
Piston Configuration Rod Configuration
Face Type Configuration
bull More compactbull Lighter weightbull Less expensive especially for higher cost
elastomers like FKM or fluorosiliconebull Less machining required for machined grooves
since grooves are smallerbull More resistant to explosive decompression
bull Less prone to compression setbull Less volume swell in liquid on a percentage
basisbull Allows for larger tolerance while still
maintaining acceptable compression squeezeand compression ratio over full stack-up range
bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Machining Specifcations
O-Ring Gland Types
O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below
Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section
Selecting an O-Ring Cross-Section
Piston Configuration Rod Configuration
Face Type Configuration
bull More compactbull Lighter weightbull Less expensive especially for higher cost
elastomers like FKM or fluorosiliconebull Less machining required for machined grooves
since grooves are smallerbull More resistant to explosive decompression
bull Less prone to compression setbull Less volume swell in liquid on a percentage
basisbull Allows for larger tolerance while still
maintaining acceptable compression squeezeand compression ratio over full stack-up range
bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Machining Specifcations
O-Ring Gland Types
O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below
Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section
Selecting an O-Ring Cross-Section
Piston Configuration Rod Configuration
Face Type Configuration
bull More compactbull Lighter weightbull Less expensive especially for higher cost
elastomers like FKM or fluorosiliconebull Less machining required for machined grooves
since grooves are smallerbull More resistant to explosive decompression
bull Less prone to compression setbull Less volume swell in liquid on a percentage
basisbull Allows for larger tolerance while still
maintaining acceptable compression squeezeand compression ratio over full stack-up range
bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces
Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression
Suggested solutions Gland design should take into
account material responses to chemical and thermalenvironments
Over-Compression
Description The seal exhibits cuts or marks which spiralaround its circumference
Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness
elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication
Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings
Spiral Failure
Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered
Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing
Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings
Extrusion (andor Nibbling)
Common O-Ring Failures
8142019 O Ring Brochure

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces
Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical
Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility
Compression Set
Description The seal or parts of the seal may exhibit smallcuts nicks or gashes
Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus
hardness elastomer Elastomer surface contamination
Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer
Installation Damage
Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size
Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer
Suggested Solutions Avoid plasticized elastomers Ensure
all seals are properly post-cured to minimize outgassing
OutgassingExtraction

httpslidepdfcomreaderfullo-ring-brochure 3236
Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures
Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling
Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces
Thermal Degradation
Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed
Contributing Factors Rapid pressure changes Low-
modulus hardness elastomer
Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)
Explosive Decompression
Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable
only by measurement of physical properties
Contributing Factors Incompatibility with the chemicalandor thermal environment
Suggested Solutions Selection of more chemicallyresistant elastomer
Chemical Degradation

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088
Rod Type sealExtrusion Gap = Bore 983088- Rod 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are
ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)
Piston Type SealExtrusion Gap= Bore 983088- Piston 983088
Rod Type sealExtrusion Gap = Bore 983088- Rod 983088

There are different methods to counter O-ring
extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

ID StretchOD Interference
For hydraulic and pneumatic piston sealing applications
The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range
and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance
For hydraulic and pneumatic rod sealing applications
The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside
diameter interference
For hydraulic and pneumatic static axial sealing applications
An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following
housing dimensions apply

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

h- housing height

Reduction in Cross-Section
Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch
Compression
The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze
HCS
Compression Squeeze
Compression Squeeze = CS - H
This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

h- housing height

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures
Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling
Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces
Thermal Degradation
Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed
Contributing Factors Rapid pressure changes Low-
modulus hardness elastomer
Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)
Explosive Decompression
Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable
only by measurement of physical properties
Contributing Factors Incompatibility with the chemicalandor thermal environment

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland
Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )
Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances
Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions
It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

h- housing height

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces
Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression
Suggested solutions Gland design should take into
account material responses to chemical and thermalenvironments
Over-Compression
Description The seal exhibits cuts or marks which spiralaround its circumference
Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness
elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication
Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings
Spiral Failure
Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered
Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing
Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings
Extrusion (andor Nibbling)
Common O-Ring Failures
8142019 O Ring Brochure

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces
Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical
Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility
Compression Set
Description The seal or parts of the seal may exhibit smallcuts nicks or gashes
Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus
hardness elastomer Elastomer surface contamination
Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer
Installation Damage
Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size
Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer
Suggested Solutions Avoid plasticized elastomers Ensure
all seals are properly post-cured to minimize outgassing
OutgassingExtraction

httpslidepdfcomreaderfullo-ring-brochure 3236
Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures
Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling
Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces
Thermal Degradation
Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed
Contributing Factors Rapid pressure changes Low-
modulus hardness elastomer
Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)
Explosive Decompression
Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable
only by measurement of physical properties
Contributing Factors Incompatibility with the chemicalandor thermal environment
Suggested Solutions Selection of more chemicallyresistant elastomer

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces
Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression
Suggested solutions Gland design should take into
account material responses to chemical and thermalenvironments
Over-Compression
Description The seal exhibits cuts or marks which spiralaround its circumference
Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness
elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication
Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings
Spiral Failure
Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered
Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing
Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures
Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling
Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces
Thermal Degradation
Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed
Contributing Factors Rapid pressure changes Low-
modulus hardness elastomer
Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)
Explosive Decompression
Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable
only by measurement of physical properties
Contributing Factors Incompatibility with the chemicalandor thermal environment
Suggested Solutions Selection of more chemicallyresistant elastomer

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces
Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression
Suggested solutions Gland design should take into
account material responses to chemical and thermalenvironments
Over-Compression
Description The seal exhibits cuts or marks which spiralaround its circumference
Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness
elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication
Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings
Spiral Failure
Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered
Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing
Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings
Extrusion (andor Nibbling)
Common O-Ring Failures

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces
Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical
Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility
Compression Set
Description The seal or parts of the seal may exhibit smallcuts nicks or gashes
Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus
hardness elastomer Elastomer surface contamination
Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer
Installation Damage
Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size
Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer
Suggested Solutions Avoid plasticized elastomers Ensure
all seals are properly post-cured to minimize outgassing
OutgassingExtraction

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures
Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling
Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces
Thermal Degradation
Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed
Contributing Factors Rapid pressure changes Low-
modulus hardness elastomer
Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)
Explosive Decompression
Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable
only by measurement of physical properties
Contributing Factors Incompatibility with the chemicalandor thermal environment
Suggested Solutions Selection of more chemicallyresistant elastomer
Chemical Degradation

Description The seal or parts of the seal exhibit a flatsurface parallel to the direction or motion Loose particlesand scrapes may be found on the seal surface
Contributing Factors Rough sealing surfaces Excessivetemperature Process environment containing abrasiveparticles Dynamic motion Poor elastomer surface finish
Suggested Solutions Use recommended gland surfacefinishes Consider internally lubed elastomers Eliminateabrasive components
Abrasion
Description The seal often exhibits discolouration as wellas powdered residue on the surface and possible erosion ofelastomer in the exposed area
Contributing Factors Chemical reactivity of the plasmaIon bombardment (sputtering) Electron bombardment(heating) Improper gland design Incompatible sealmaterial
Suggested Solutions Plasma-compatible elastomer andcompound Minimize exposed area Examine gland design
Plasma Degradation
Description The seal exhibits foreign materials on thesurface andor within the O-ring
Contributing Factors Process environment depositionReactions or degradation of the elastomer Non-semiconductor-grade elastomer
