Polyfit polyethylene fittings for use with polyethylene PE, polypropylene PP and PEX pipes for use in drinking water and water supply networks with a pressure of 16 bar for 20 to 63 mm diameter and 10 bar for 75 to 110 mm diameter It is designed. This innovation is in the unique design of the head and its special split and O-ring. In this type of connection, you can easily put the pipe inside the connection with complete sealing by loosening the screw and then tighten the corresponding screw. In this type of connections, due to the use of raw materials with UV stabilizer, there is the ability to resist ultraviolet rays (UV) and can be exposed to sunlight in Expose applications.
