The PosiGrip Method


PosiGrip is a method of joining flanged fittings, flanged valves, and other equipment with integral flanged ends to plain-ended, HDPE pipes and PVC pipes, with all the advantages to ductile iron and steel pipes with welded, grooved, or screwed systems.


How it Works


Like all the best ideas, the working principal of PosiGrip is a simple one. Slide the flange and gasket over the plain-ended pipe so that the end of the pipe and flange are in line. When the PosiGrip is brought to mate against the existing flange, and the flange bolts are tightened, it creates a compression seal against the mating flange and down on the pipe surface.
