ABSTRACT:
A tool for use by pipefitters in joining a length of pipe to a fitting in which one end of the pipe is accommodated with a predetermined spacing between the end of the pipe and an internal shoulder within the fitting. The tool comprises jaws which may be clamped on the pipe when the end of the latter abuts the shoulder and includes shims movable from a position spaced from the pipe toward the latter to occupy a position between the jaws and the adjacent free end of the fitting, thereby providing for a predetermined spacing between the free end of the pipe and the shoulder of the fitting.
