Water working pressure high to1.6MPa (232psi);
Only need 8 second to finish install a connector, very easy install;
Perfect choice to replace traditional pipe fitting.
Press fitting range: Coupling -- Equal coupling, Reducing coupling, Adjustable coupling, coupling with screw; Elbow -- equal elbow, reducing elbow, elbow with plain end, elbow with screw; Tee -- equal tee, reducing tee, tee with screw; Other fittings -- Pipe cap, pipe bridge and Flange.
Stainless Steel Press Fit Pipe System
Hopewell press fitting system joins pipe without welding or bolting, can be widely used in cold and hot water supply, heating supply, fire protection, medicinal gas, industrial petroleum pipeline system etc. It has already replaced welding fittings in most Europe countries, Asia countries and some other countries.
