Project Description


DYCO PPSU Cold Expansion Fittings—Red Expansion Ring

DYCO PPSU Cold Expansion Fittings designed on the basis of the elastic memory of the PE-Xa pipe & ring. A Patent Expansion Ring will be fitted over the pipe end follow the right direction; both the pipe and ring will be expanded a defined number of times using a battery expansion tools, then pushed to the positionings of the DYCO fittings.

We offer full sizes including typical 16mm, 20mm, 25mm, 32mm for couplings, reducers, elbows, tees, tap connectors and threaded adaptors (M/F). Not only all DYCO PPSU Cold Expansion Fittings and Rings are marked the pipe specification clearly, but the inner & master package labelled as well, absolutely quick and easy for installer.
