Beschreibung
Zusammenfassung:	A telescopic joint in low pressure corrugated plastic pipe. The joint includes a one-piece elastomeric gasket which functions as a seal between the telescoped pipes. The gasket has a sealing portion adapted to be disposed in a groove in one of the pipes and an anchoring portion adapted to be disposed in an adjacent groove. As the pipes are telescoped together the anchoring portion is trapped in the groove and anchors the sealing portion in place as it is compressed due to an interference fit with the pipes as the joint is made.
