ABSTRACT:
Pipe coupling system and method in which a tapered wall is formed on one of two tubular pipe members for press-fit engagement with a wall of the second pipe member, and the two pipe members are pressed together in an axial direction to bring the tapered wall and the other wall into direct press-fit engagement with each other. The two pipe members can, for example, be a length of copper water pipe and a copper pipe fitting, and in certain disclosed embodiments, the pipe members are drawn together by a tool having axially movable jaws which engage the pipe members and are driven together in the axial direction by an actuator and linkage which move in a perpendicular direction.
