Over the years, PP compression fittings have been widely used in agricultural irrigation, drinking water supply and other piping systems.

Advantages:

safety and sanitation

simple installation

quick connection

good water tightness

durability

      2. Where do PP compression fittings 

      can be used?

      PP compression fittings are used 

      inagriculture gardening,and residential areas, 

      municipal engineering and sports fields. The

PP compression fittings can connect with HDPE pipe. 

You can see it at the follow picture.

Besides connecting with HDPE pipes, PP compression fittings can be used with:

①  Saddle clamp

②  PVC threaded fittings

③  PVC valves, such as compact ball valve, butterfly valve, etc.

④  HDPE pipe and fittings

⑤  drippers, sprinklers, filters, water tanks, pumps, etc.
