Abstract
An apparatus and method are shown for installing a metal transition end on an open end of a length of plastic pipe having an outer diameter and an inner diameter by placing a stiffener sleeve within the inner diameter of the plastic pipe at a point which is circumscribed by the metal transition end. An actuating sleeve, carried on the draw rod, allows the stiffener sleeve to be installed in a desired location within the open plastic pipe end by using the draw rod to first position the stiffener sleeve in the desired location. The metal transition end is provided with an internal relief groove which accepts any excess plastic material forced past the stiffener sleeve during the installation process.
