Abstract
A self-restrained pipe joint system and method of assembly to connect two lengths of pipe in a mechanical joint, which maximizes the advantages of both restrained push-on joints as well as mechanical joints, as are known commonly in the art. The invention has application to long-run pipe lengths as well as to appurtenances, including fittings and connections. The gasket contains locking members that act to restrain separation upon the instance of any force tending to separate the connected pipe lengths
