Construction of Dk-Lok Fittings
Dk-Lok Tube Fittings have been designed specifically forthe many demanding applications chemical, petroleum,power generating, pulp, paper and various types ofmanufacturing industries. They provide a highly reliable,leakproof and torque free seal on all tubing connections.Dk-Lok Tube Fittings are commonly used oninstrumentation, process and control systems or any otherapplication where a high quality tube fitting is required
The Dk-Lok body, nut, back ferrule and front ferrule aremanufactured under very close tolerance control andmonitored through Statistic Process Control and are Heat-Code Traceable.
The twin ferrule design performs leak proof sealing with allassembly and reassembly motion being transmitted axiallythrough the tubing. This results in no radial movement of thetubing upon assembly and reassembly. Therefore, the tubingis not stressed and the mechanical integrity is maintained.This is the result of close tolerance control in machining,surface smoothness and hardness of each and every part ofthe Dk-Lok tube fitting. Through this swaging action, theDk-Lok fitting becomes integrated mechanically with thetubing connected.
Dk-Lod fittings are available in Stainless Steel, Brass andCarbon Steel as standard materials, and can be manufacturedfrom various materials upon request. Dk-Lok fittings aretested according to JIS B2351 & BS4368 standards.

Technical Information
Standard of Quality for Dk-Lok Fittings
Tubing has many benefits over piping. Since tubing is able to be bent, this allows lower pressure drop due to fewerconnections. This in turn reduces costs because of lessfabricating manpower. Dk-Lok connections do not requirethreading or welding, and are assembled by standard wrenchmake-up. This results in less assembly and maintenance costs.
Tubing & Tube Fitting Benefits
For safe, reliable and leak-free seals, tubing should beconsidered as a fitting component. Quality Dk-Lok fittingsprovide the best performance when good tubing is used. Careshouldbe taken and general rules followed to have good tubingconnections.
Tubing Selection
Tubing - General Rules
1. For leak-free sealing, the tubing surface is very important. The Tubing must have a good surface free from scratches, draw mark, flat spots or dirt.
2. In case of welded tubing, it should not have a visible poor bead on its outside diameter.
3. Using like tubing and fitting material is essential for thesame thermal compatibility and corrosion resistance. The tubing material should be compatible with the processfluid, temperature and environment.
4. Tubing must be softer than fitting material. When tubing and fittings are made of the same material, the metal tubing must be fully annealed.
5. Tubing hardness must be selected according to the information in the table 2 to 8.
6. Do not select a too thin or thick wall. A too thin wall may collapse and a too thick wall may not properly be deformed by the ferrule action. The wall thickness selection should be based on the applicable pressure, temperature, shock and vibration.
7. Tubing with oval or out-of-roundness appearance may not fit into the fitting. Do not force the tubing into the fitting, it may damage the fitting sealing system of the nut, ferrules, or the body.
Purchasing the tubing based on the industrial standards suchas ASTM or other equivalent specifications doesn't mean thatyou have the right tubing when we see other variables.
See variables below for taking care of your tubing1. Material Grade 2. Weld or Seamless3. O.D. and Tolerance4. Wall thickness and Tolerance5. Hardness 6. Ovality (Shape)7. Concentricity 8. Surface finish
Tubing Temperature Ratings
The Maximum and Minimum operating temperaturesfor various tubing material
Allowable working temperature
When Elastomer seal is used in the fitting, care must be takenfor allowable working temperature. See working temperaturebelow.
Temperature De-rating Factors
The allowable working pressure is determined by varioustemperatures.
To determine the working pressure at the specifictemperatures, multiply the working pressure at ambienttemperature shown in table 2~8 by the factor shown in table 1.
Example : Tube SS316 1/2” O.D. x 0.065” at 700 F.5100psi °x 0.82 = 4182psi.Therefore 4182 psi is the maximum allowableworking pressure of SS316 1/2” O.D. x 0.065”wall tubing.
Tube cutting and de-burr both ends
Use tube cutter for straight cutting of tubing and clean metal chips from both I.D. and O.D. of the tube with deburring tool.Hacksaw can be used for cutting improper size by tube cutterand hacksaw blades should have at least 32 teeth per inch.
Tube bending
Bendability is one of tubing benefits against piping, this causes fewer connections therefore fewer leaks potentialityof the system.Proper tube bending practices ensure against potential leaks of hazards.* Bend prior to installing fittings.* Use tube bender, Do not bend a tube placed in the fitting.* Do not bend close to fitting, allow a certain straight
distance from fitting to the starting point of tube bend.For further details, see page 58.

Working pressures are based on allowable stress value of 18,700PSI (128,800kPa=1288bar) as specified by ASME B31.3-1999 over the temperature range of -29°C to 38°C (-20°F to 100°F).Safety Factor = 3.75:1, considering ultimate tensile strength 70,000PSI (482,300kPa=4,823bar)Pressure calculations are based on maximum O.D. and minimum wall thickness and no allowance is made for corrosion and erosion.For working pressure per ASME B31.1, multiply value by 0.94
When Special Alloy Tubing is Selected, we recommend : Fully Annealed Seamless(or Welded and Cold-draw, wherepermitted) Alloy Tubing to the ASTM specification as shown below. Tubing should be free of scratches for bending orflaring.
Special Alloy Tubing
DK-Lok tube fittings are designed for a wide range of leak-free application including gas leak proof and vacuum service.Gases can escape even the most minute leakpath due to their small molecules, Tube must therefore be carefullyhandled not to get scratched.Use heavier wall tubing for gas service. Heavy wall tubing resists ferrule action by coining out minor defects of the tubesurface and thin wall tubes may collapse with little resistance to ferrule action.
For Gas service, use the tubing of the un-shadowed section in table 5 - 8.
Tubing for Gas application
DK- Lok Fittings in S316 Stainless Steel provide highly reliable performance from Cryogenic Temperatures to HighTemperature Levels.S316 Stainless Steel Temperature Rating : -321°F to 1200°F (-196°C to 649°C)Cryogenic Temperature are considered to be Temperatures Below : -100°F (-73°C)

Many Dk-Lok tube fittings have a male or female pipe end. These ends sometimes have a lower pressure rating thanthe pressure rating of the tube fitting end.
Pipe Thread
Pipe thread sealant is essential to ensure leak-free seal. Since the Teflon tape is commonly used, we provide information of recommended tape width, as well as the numbers of thread to be wrapped. The TeflonTM tape fills the voidsbetween threads and prevents galling on pipe threads. The sealant usually contains a lubricant.

* ASME B1.20.1-NPT
The ratings shown above are based on ASME B31.3-1999Female pipe ends have lower ratings than male pipe in a given size due to the inner and outer diameters of female threads being larger than those of male pipe ends.
The ratings shown above are reference only.
Note: 1. Wrap TeflonTM Tape clockwise from first thread. Do not overhang the first thread, as the tape may get intothe fluid system.
2. TeflonTM tape has a temperature limit of 230°C( 450°F).
Note: The information shown in table 1-10 are not for design purpose, but for reference only. The accuracyof information is not the liability of our company.

The ISO 7/1 is a tapered thread that is sealing threads working by interference fit. This still requires thread sealant forpressure-tight seal by filling the voids between threads further this prevents galling on piping threads. The sealant usuallycontains a lubricant.The 7/1 is described in following codes.
1. BS 21(BSPT) 2. JIS B0203 (PT) 3. ISO 7/1 4. DIN 2999 (male thread only)
The 7/1 looks similar to the NPT thread. See how different they are as illustrated below.

SAE Fittings
Dk-Lok SAE Straight O-Ring Seal Fittings are of positionable feature and provide connection tube to straight threadboss. Further this has an advantage of eliminating welding and brazing process when used as bulkhead fitting onthin wall tanks or vessels.
These fittings are designed and manufactured to SAE standards as below:Male or External Fitting End Dimensions to SAE J514Straight thread to SAE J475 (equivalent to ANSI B1, 1 or ISO R725)Female or Internal Straight Thread Boss to SAEJ1926. See diagram below.
Installation Instruction
Step 1. Ensure the locknut is fully raised.
Step 2. Lubricate the O-Ring with a light oil or petroleumand turn the fitting into the straight thread boss untilthe metal washer is in contact with the boss
Step 3. Position the fitting by backing it out (not more than 1 turn counter-clockwise)until the Dk-Lok fitting is oriented Iin the desired direction.
Step 4. With a back up wrench, hold the wrench pad and tighten the locknut until the washer is set against the face of the boss.
Details of SAE Internal Straight Thread Boss
O-Ring and straight thread size for SAE Fitting Bosses
a. Diameter U shall be concentric with the thread pitch diameter within 0.13 full indicator reading (FIR)and shall be free from longitudinal and spiral too marks. Annular tool marks up to 2.5 Micro meters max. shall be permissble.
b. This is the Maximum recommended spotface depth to permit sufficient wrench grip for the proper tightening of the fitting of locknut.
c. If the face of the boss is on a machined surface, dimensions Y and S need not apply as long as R 0.25/ 0.375 is maintained to avoid damage to the O-Ring during installaton.
d. Tap drill depths given require the use of bottoming taps to produce the specified full thread lengths. Where standardtaps are used, the tap drill depths must be increased accordingly.

O-Seal Connector
Dk-Lok O-ring seal fittings provide leak-tight sealing on both vacuum and high pressure with a smooth & flat surfaceperpendicular to the threaded port to ensure metal to metal contact.
The standard Buna N O-ring is contained in a precision groove to prevent O-ring extrusion at high pressure and for acontrolled squeeze in a vacuum service.
When installing an O-ring seal fitting:
1. Hand-tighten it until the squeeze on the O-ring can be felt during the last 1/4 turn2. Snug the fitting lightly with a wrench
When connecting & disconnecting the tubing to the O-ring fitting:
1. Use a back-up wrench on the fitting hex so it does not turn while the nut is being tightened at the tubing connection.2. When disconnecting the tubing also use a back-up wrench so the fitting does not turn3. For a recessed port, use a thin back-up wrench (1/8")to hold the fitting hex (Fig.3).

Dk-Lok Welding information
Dk-Lok weld ends are constructed to Schedule 80 wall or greater.The first step is to remove the nut and ferrules from the Dk-Lok fitting to protect them from weld heat and cover thethreads with a protective device (i.e. another nut or a plug) DP to protect the Dk-Lok port threads & sealing surface from weld spatter. Only finger-tighten the protective device so that you can use it many times.The second step is to tack weld at four positions 90° apart to hold the fitting in place to ensure alignment andconcentricity of the components, then complete the weld.
A, B & L are approximate figures in finger-tight.
All dimensions are in millimeters unless otherwise specified and only for reference subject to change.

Dk-Lok maintains unbelievably tighttolerance on its each and every part.Dk-Lok tube fittings are monitoredand gauged throughout process.This assures Dk-Lok consistency and makes Dk-Lok fittings gaugable.
This no-go gauge is the useful toolto inspect if the fittings are pulled up1-1/4 turns from the finger-tightposition. When the gauge doesn't fitthe gap between the nut and bodyhex, the fitting is tightened 1-1/4 turnsfrom the finger-tight position.If the gauge fits the gap, the fittings is not fully tightened.

INSTALLATION INSTRUCTIONS
Dk-Lok is supplied finger-tight and ready for immediate use. Therefore fitting disassembly is not necessary for
Make sure the nut is finger-tight. Put the tubing into the Dk-Lok tube fitting until the tube end bottoms on theshoulder inside the fitting.
Tighten the nut 1-1/4 turn with a wrench by holding thefitting body with a back up wrench.
Marking the nut at the 9:00 o' clock position may benecessary for counting the number of turns as the mark willstop at the 12 o' clock position after 1-1/4 turns.
* Only 3/4 turn from finger tight is required for sizes 1/8", 3/16",3mm and 4mm.

Re-assembly Instructions
Dk-Lok connections can be used many times. Prior to re-assembly, ensure the components are clean and free of defects.
Step 1.Insert the tubing with pre-swaged ferrules and a nut into the body until the front ferrule seats firmly in the fitting body.
Step 2. Hand tighten the nut. Then rotate the nut with a wrench to the original 1-1/4 tight position(sharp rise in torque is felt at theoriginal position) and snug slightly with a wrench.
Tube handling during installation
1. Do not force the tubing into the fitting when it does not smoothly go in. It may be a deformed oval or have burs at the tubing end.
2. It is important to use the proper tube cutter and maintain a sharp cutting wheel on it always.
Proper Tube Handling
Good handling practices can greatly save the good surface finish of the tubing supplied.
* Tubing should be stored vertically not horizontally to avoid collection of dirt and contamination. Cover the tubing when youhave to keep horizontally.
* Tubing should never be dragged across cement, asphalt, gravel or any other rough surface.* Tubing should never be dragged out of a tubing rack.* Tube cutter wheel and hacksaw blade should always be sharp.* Try not to take deep cuts with each turn of the cutter or stoke of the saw.* Tube ends should always e deburred* If possible, tubing ends should be plugged so any foreign materials will not fall inside.* Nylon or soft plastic tubing should use Tube Insert (DI) as sealing on the O.D. of the tubing needs a certain amount of
tube resistance for a tight seal.
These help assure the tubing goes all the way through the fitting without damaging Dk-Lok sealing system.
