Abstract
This invention relates to a composite flexible seal for providing a fluid tight joint between a pipe section and the inside surface of a receiving opening. The seal includes a slightly elongated tubular body formed of an elastomeric material and a spring-like metal snap ring encapsulated within the body. The ring can be collapsed inwardly upon iself reducing the outside diameter of the body and allowing the seal to be inserted into the receiving opening. Once situated in the opening the ring is expanded causing the seal to be locked in fluid tight contact against the wall of the opening. A pipe section is inserted into the seal opening to complete the joint.
