Parker’s triple-lok 37° flare tube fittings have been used in industry since mr. Parker pioneered the product in the 1930s. The 37° flare fitting is the most popular industrial tube/hose fitting connection in the world. Today, parker offers a broad range of triple-lok fittings meeting sae j514, iso 8434-2 and military standards and specifications. The triple-lok design is quite simple. The tube fitting consists of three pieces: the body, the nut and the sleeve. The tube end is flared at a mating 37° angle and sandwiched between the fitting nose (seat) and the sleeve creating an effective seal between the fitting nose and tube flare or hose. Parker’s triple-lok fittings are manufactured in steel, 316 stainless steel and brass for optimum fluid compatibility and corrosion resistance. Furthermore, available sizes range from 1/8" tube o. D. To 2" tube o. D. In several configurations. Adaptability to global ports is another key benefit of triple-lok. (standard ports include: sae, straight thread iso-6149, npt, bspt, bspp and din. ) The triple-lok tube fitting is also readily available for metric tubing and hose adapter applications. Simply by changing the industry standard sleeve, the same triple-lok body can be adapted to metric tubing in sizes ranging from 6 mm tube o. D. To 38 mm tube o. D. Likewise, by using only the body without the nut and sleeve, the triple-lok fitting is used as an industry standard hose adapter.

|Weld Nipple fittings Principle :- |
weld nipple fittings with an O-ring seal between weld nipple and fitting body give impressive tear out resistance and sealing integrity.
Weld nipples SKA conform with DIN 3865 form A.
Fitting bodies and nuts are fully interchangeable for weld nipple and for 2/progressive ring fittings of the same series and external tube diameter.
Materials and surface protection:
Steel phosphated and oiled, O-ring of NBR (e.g. Perbunan).
Stainless steel 1.4571, O-ring of FPM (e.g. Viton)
Welding suitability and weldability
Weld nipples, tube bend weld nipples and ASK types made of steel are weldable according. to usual techniques. Types made of 1.4571 (stainless) are suitable for arc welding. The welding filler should be selected in accordance with DIN 8556 part 1 with consideration of the type of application and the welding technique.
We recommend the use of tubes in steel and stainless steel as illustrated in this catalogue.
Nominal Pressure (PN) of complete weld nipple fittings
The nominal working pressure (PN) of a complete weld nipple fitting is dependant upon the least rated component, i.e. tube, weld nipple or fitting. The component out of these three with the lowest rated pressure or working pressure determines the nominal pressure (PN) of the complete fitting.
|Permissible temperature range|
For weld nipples, tube bends with weld nipples and ASK types of steel with O-rings of
1. NBR (e.g. Perbunan): –35°C to + 100°C
2. FPM (e.g.viton): –25°C to + 200°C
without pressure reductions
For temperature range and necessary pressure reductions for weld nipples, weld nipple fittings and ASK types of 1.4571, see corresponding page.
1. Cut off the tube square, deburr and bevel the end of the tube in conformance with DIN 2559.
2. Slide nut onto the weld nipple.
3. Weld nipple to the tube according to normal welding procedure. The tube and nipple must be aligned.
Before welding, please remove the nut.
4. Dress the weld on the inside and outside.
5. Fit the O-ring without twisting. The taper, the nut and the cone must all be clean.
6. Oil the nut, taper and cone and thread before assembly
7. Screw on the nut by hand. Fully tighten using a spanner with 1/4 to 1/2 turns.
Make sure that the tube with the weld nipple is assembled straight and without in built stress.
