Abstract
The coupling includes a mandrel and a coupling outer sleeve. In a method for installing the coupling on a pipe, the mandrel is inserted into the inner diameter of an end of pipe with an outboard end of the mandrel protruding from an end of the pipe. Then the outer sleeve is positioned over the pipe to form a length of substantially concentrically arranged, overlapping parts of the mandrel, the pipe and the sleeve. Then the sleeve is crimped over at least a portion of length, which engages the pipe between the sleeve and the mandrel. Either before or after sleeve is crimped over the pipe, the sleeve is connected to the outboard end of the mandrel.
