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 adaptor fittings are consisted of 5 palstic accessories:
