ABSTRACT:
An end sealing member joined to the ends of a pipe for cooperation with a complementary end sealing member on another pipe to seal the joint formed when at least two such pipes are joined in end-to-end relationship. Each end sealing member has upstanding members extending into the surface of the pipe to seal the interface between the sealing member and the pipe to which it is secured. The exposed surface of one sealing member is configured to sealingly engage the exposed surface of a complementary sealing member when the one sealing member is telescoped over the other in forming the joint between the two pipes.
