HDPE Compression Fittings, PP compression fittings, HDPE Compression Male Adaptor, hdpe male adaptor, male adaptor hdpe, hdpe male threaded adaptor, Compression male adaptor, HDPE Pipe Male Adaptor, Poly Male adaptor, PP compression male adaptor
Poly compression fittings are an age-old method of joining two pieces of poly pipe together, with an o-ring or bush and a screw cap working together to clamp the pipe ends within the fittings. With a clean pipe and a new fitting, the grip is strongest, and when properly installed, will last for many years without leaking. The fittings are mainly made of polypropylene black co-polymer (also called "PP compression fittings").
A HDPE compression male adaptor fitting is used to join a length of HDPE pipe with a female-threaded valve or tap. PP compression male adaptor fittings can be manufactured in a diameter sizing from 20*1/2"mm to 110*4"mm, with pressures up to 16 bar. The HDPE compression male adaptor fittings are made from high quality PP-B material that is resistant to etching by numerous chemical substances, and to UV rays, and are suitable for outdoor use. 
PP compression male Elbow fittings are consisted of 5 plastic accessories:

Benefits Of PP Compression fittings
By comparison of the other fittings, poly pipe compression fittings provide outstanding physical and performance benefits:
By comparison of the other HDPE fittings, HDPE electrofusion fittings repute more benefits:
* Fast assemble & disassemble, Simple installation:No welding, No special tools required, easily assembling & disassembling, those makes PP compression fittings more & more popularly used, especially for irrigation systems.
* lower installation costs & labor costs: HDPE compression fittings is a fittings use a mechanical connection method, fast to install & less install workers will be required.
* Perfect watertight: The unique design & NBR "O" rings ensure Poly compression fittings a perfect watertight for long time use.

▪ Tests on finished product:
- Watertightness with internal hydrostatic pressure
with no axial strength (EN-714).
- Pressure watertightness with outer hydrostatic
pressure (EN-911)
- Pull out resistance test (EN-712)
- Internal pressure test with "bending" (EN-713)
- Test of insertion of pipes in o-ring.
