Rifeng Multilayer Fittings

Rifeng Multilayer Fittings


RIFENG Universal "H", “U “and “TH” Profile Crimp Fittings feature 2 EPDM O Rings on each fitting insert which provide an interference fit to the inner wall of the pipe and which when combined with a pressed stainless steel outer pressure sleeve provide a water tight seal. They can be assembled and pressed within a matter of seconds. Each stainless steel pressure sleeve features inspection windows which provide for installer joint reassurance. The pipe is inserted into the fitting and the windows confirm that it has been fully inserted prior to pressing. The bodies are made of brass, while the sleeves are of stainless steel. The range of fittings is comprehensive and includes couplings for connecting to existing Copper and PEX plumbing systems. Pressing is by means of a simple manually or electrically operated Pressing Tool. The Pressing Tool is universal in application in that the Pressing Die sizes may be changed very easily and quickly.
