A compressible annular gasket for providing a fluid-tight seal between a first tubular member having an annular groove and an adjacent ridge and a smooth annular section of a second tubular member when the first tubular member and the smooth annular section are in a relative surrounding and surround

A compressible annular gasket for providing a fluid-tight seal between a first tubular member having an annular groove and an adjacent ridge and a smooth annular section of a second tubular member when the first tubular member and the smooth annular section are in a relative surrounding and surrounded relationship. The compressible annular gasket includes an anchor portion adapted to be disposed in the annular groove and an elongated portion adapted to extend across the adjacent ridge when the anchor portion is disposed in an adjacent groove. The elongated portion makes contact with the annular section when the first tubular member and the smooth annular section are in a relative surrounded and surrounding relationship.

1. A compressible annular gasket for providing a fluid-tight seal between a corrugated pipe having an annular groove and an adjacent ridge, and a smooth annular section of a second member, when the corrugated pipe and the section are in relative surrounded and surrounding relationship, comprising:a) an anchor portion shaped to conform to a groove in a corrugated pipe, said anchor portion accommodating insertion into said groove and being large enough to prevent said anchor portion from being pulled between an annular ridge of said corrugated pipe and a smooth annular section when said corrugated pipe and said annular section are in relative surrounded and surrounding relationship; and, b) an elongated portion extending from said anchor portion and adapted to extend only partially across said annular ridge when the anchor portion is disposed in said groove, said elongated portion being adapted to make sealing contact with said annular section when said corrugated pipe having said groove in which the gasket is received and said smooth annular section are in relative surrounded and surrounding relationship.
