Abstract: A pair of pliers for connecting or disconnecting a push-fit coupler with an internal toothed grab ring has forked, U-shaped opposing jaws, one of which is sized to fit to hold a cylindrical pipe connected to a push-fit coupler, and the other jaw sized to hold the exterior support sleeve of the coupler, so that squeezing the pliers will compress the internal grab ring, causing the teeth to splay thus freeing the pipe so that it may be removed from the coupler. The pliers may also be used to splay the teeth while inserting a pipe into the coupler.

Abstract: A crimping tool for pipe fittings has a pair of semi-cylindrical opposing jaws with opposing ends, pivotally attached at one end of each, for closing and opening movement about the pivot axis. When closed, the jaws define a cylinder for engaging a pipe or other cylindrical element to be crimped. The other ends of the jaws have integral extensions that meet when the jaws are closed and are clamped together by a simple crimping force assembly comprising a threaded eyebolt, the eye end being pivotally attached to the end of one jaw extension. The bolt swivels in and out of a slot in the other jaw extension. A nut on the other end of the eyebolt is used to compress the two jaw extensions together. In another embodiment, the jaws have annular grooves on their inner surfaces to accommodate the male ridges of ProPress® pipe fittings.
