Abstract: A locking annular gasket, for providing a seal between a tubular member and a smooth annular section, includes an annular gasket portion and a locking member. The annular gasket portion seals a gap between the smooth annular section and the tubular member. The locking member is secured to the gasket portion for holding the gasket portion in place while the tubular member and the smooth annular section are assembled.

Abstract: 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.
