ABSTRACT:
A pipe coupling for joining separate segments of pipe together in a fluid tight manner. A connector is fixedly secured to one pipe section with the retaining nut being movably mounted on the other pipe section. The retaining nut is to be threadably secured to the connector. In between the connector and the pipe section is located a sealing arrangement which includes a thin walled grip ring. This grip ring includes a plurality of biting members. When the retaining nut is tightened on the connector, these biting members imbed into the wall surface of the pipe section thereby longitudinally fixing the position of this pipe section relative to the connector and maintaining a fluid tight established relationship.
