ABSTRACT:
A tool for separating a gasketed pipe joint includes a body comprising a relatively thin member formed into a partially cylindrical shape having spaced-apart forward and rear edges; and an arcuate reinforcing collar attached to an outer surface of the body adjacent the rear edge. A driving apparatus for the tool includes a first driving ring adapted to be mounted around one of the pipes and sized to bear against the gasket release tool; a second driving ring adapted to be mounted around the other one of the pipes and sized to bear against the socket; and apparatus for drawing the first and second driving rings together so as to drive the gasket release tool into a pipe joint.
