LET-LOK® type connectors
Description and application
LET-LOK® connectors for pipes are designed mainly for chemical, petrochemical, pharmaceutical and power in-dustry, nuclear power plants and process engineering. Designed to work under high pressure, vacuum, vibration, high temperatures, and where high leak tightness of connections is required. Made in accordance with an industrial specification for two O-ring connectors in the highest quality applications. To meet all production requirements, fully automatic machining centres are utilized to make products which undergo 100% quality control at different stages of production process.LET-LOK® connectors are available as couplings (to connect several pipes) and connectors (to join pipes with fittings with male or female thread).
nut body front ferrule
back ferrule
The mechanism of a coupling causes gripping and sealing of connection on the cone of the body and front ferrule. The pipe deforms and the seal is made only by metal parts which allows to get the maximum working temperature of about 650°C, both for high pressure and vacuum. Such connection provides perfect leak tightness without un-necessary stress.
Structure of LET-LOK® fitting
Basic advantages of LET-LOK® connectors
- A wide range of pipe diameters, from 2 up to 50 mm and from 1/16” up to 2”.- Maintains high leak tightness of the connection even after repeated assembly.- Very high leak tightness in high pressure and temperature conditions, vacuum, vibration and rapid changes of
pressure.- Made in 4 material versions: stainless steel AISI 316, brass, Monel 400 alloy and Hastelloy C-276.- To facilitate identification, each connector is marked with a material name it is made of and with pipe outside
diameter.- Connectors are assembled using a regular spanner which lowers the costs of installation and service.
The pipes used with LET-LOK® connectors
In order to ensure maximum reliability, durability and safety of the connection, special attention should be given to the matching of a pipe to an application. The pipes made of AISI 304 or AISI 316 stainless steel in connection with stainless steel LET-LOK® connectors can be used in the widest range of applications. The pipes should be made in accordance with the requirements of ASTM A213, ASTM A269 standards or equivalent.
When choosing the pipe, notice the following:- The pipe surface should be smooth without scratches, clean from dirt.- The pipe must not be flattened or oval. It can damage the connector and cause leakage.- The pipe should be annealed and made of material which is softer than the material of the connector (90 HRB
or lower).- The thickness of the wall must be adapted to the working pressure in the installation.
Copper pipes can be also used but in connection with brass LET-LOK® fittings (contact TUBES INTERNATIONAL® Sales or Technical Department).

INSTRUMENTATION - valves
Top grade, precision valves of different types (ball, needle, check valves and many other) used in control and measuring equipment for chemical, petrochemical, pharmaceutical and power industry, nuclear power plants and process engineering. Available in many different versions depending on working temperature, pressure and con-nection size. Made of AISI 316 stainless steel as a standard.
The construction of ball valve (on the example of H-6800 series valve):
Ball valves are used to fully open or close the flow path. Should not be used in the intermediate position.
panel mounting option
connections:LET-LOK®, male and female threads
ball sealing: TFM, PCTFE, PEEK
body sealing: PTFE, PEEK
stem sealing: PTFE, PEEK
Types of main seals (ball) used in ball valves:
material valve type working temperature range characteristics and seals applications
TFM®1600
H-6800 from -34°C up to +210°C Modified PTFE with the same chemical resistance, but with bet-ter pressure characteristics. Compared to standard PTFE, it un-dergoes less deformation under pressure load and has greater ability to regain its original shape once the pressure load is re-moved.
H-500 from -28°C up to +204°C
H-700 from -34°C up to +204°C
PCTFE H-6800 from -40°C up to +140°CModified PTFE with the same chemical resistance. Recom-mended for low temperature applications e.g. nitrogen or oxy-gen.
PEEKH-6800 from -34°C up to +260°C Very good resistance to chemicals and hydrolysis, very high me-
chanical strength and dimensional stability. Retains rigidity and shape in its working temperature range.H-500 from -28°C up to +232°C
PFA H-800 from -54°C up to -149°C Modified PTFE with the same chemical and temperature resist-ance, but with better mechanical properties.
PTFE H-500 from -28°C up to +186°CVery good resistance to chemicals, aging, hydrolysis and weath-er conditions. Low coefficient of friction. Perfect sealing material for general purpose application.
SS PTFE H-500 from -28°C up to +232°CPTFE filled with stainless steel powder. It has better tempera-ture and pressures properties, lower deformation factor with the same chemical resistance as standard PTFE.
UPE H-500 from -28°C up to +122°C Very good chemical resistance, low coefficient of friction. It is used mainly in the tobacco industry.

INSTRUMENTATION - valves
Needle valves (depending on the type of a valve and stem) may be used to fully open and close the flow path, to regulate the flow rate or to dose the media.
Needle valves
The construction of needle valve (on the example of H-300 series valve):
Four types of stems used in H-300 series needle valves:- A - regulating stem,- B - standard V-stem type, close-open valve position,- C - with non-rotating stem, reduces friction, recommended for high pressure gases and large number of cycles,- D - with non-rotating stem with soft removable seal, assures lower torque when tightening, recommended for
high pressure gases of high purity.
stem types (needles)D C B A
panel mounting option
connections:LET-LOK®, male and female threadsstem seal: PTFE
Check valves open flow in one direction at the set difference between pressure values. Release valves (overflow) open the flow when pressure in the system rises above the set value. Excess flow valves close the flow if pressure drops behind the valve, when e.g. installation bursts. All these valves are equipped with springs calibrated for a defined pressure value.
Check, release and excess flow valves
The construction of check valve (on the example of H-400 series valve):
sealing:Viton, NBR, EPDM,CR, Kalrez, PTFE
connections:LET-LOK®, male and female threads
opening pressure (PSI):1/3, 1, 3, 5, 10, 25, 50

Check valve H-400 type
INSTRUMENTATION - valves
Check valve designed for instrumentation applications. Closed as a rule, the valve opens when the pressure dif-ference between inlet and outlet is higher than the valve opening pressure (depending on a spring applied). The valves are set with one of the opening pressure values: 1/3 PSI (0.02 bar), 1 PSI (0.06 bar), 10 PSI (0.68 bar), 25 PSI (1.7 bar) or 50 PSI (3.4 bar). H-400 series comprises 5 groups of valves: basic H-400, high pressure H-400HP (up to 410 bar), one-piece H-400OP, H-400OPA and H-400A with adjustable opening pressure. All valves are pressure tested before shipment.
H-911High pressure emergency excess flow valve. Sizes from 1/8” to 1/2”. With LET-LOK® connectors and threaded connections. Working pressure up to 410 bar. Working tem-perature up to +204°C.

Top quality, high pressure relief valve for general purpose application, available in one size, 1/4. There are two ver-sion of the valve, one is for low pressure (working pressure:15.5 bar) and the other for high pressure HP (working pressure 414 bar) in 8 pressure range options for fully open mode. The valve is marked with the colour of a spring and label on the valve in different way for each pressure range option (from A to H). The colour-coding helps to identify the valve’s opening pressure range.

Needle valve SM-1000 type
INSTRUMENTATION - valves
High pressure needle valve. As a standard equipped with self-centring, non-rotating stem (needle) extending ser-vice life of metal sealing surface and ensuring leak tightness at large number of cycles. In working temperature above +150°C (above +100°C for Graphoil graphite sealing) the maximum working pressure of 690 bar must be reduced in consultation with TUBES INTERNATIONAL® Sales or Technical Department. All valves are pressure tested and marked before shipment.
Also available:
- other types of needle valves of SM-1000 series (valves with drainage, with male thread at the inlet, with three outlets and 90° valves).
- valve blocks (2, 3, 4 and 5 valves), based on the SM-1000 valve series, with female thread, male thread and flanged,
- SM-1000 needle valves and valve blocks made of other materials (Monel, Hastelloy, Inconel, titanium, Duplex steel and many other).
