Abstract
A tubular sealing member defines a bore having an open mouth, plus several spaced, annular sealing members in the bore to grip and seal a tubular projection. In accordance with this invention, at least some of the spaced, annular sealing rings define, in cross section, flexible elongated projections which, in turn, define longitudinal axes which incline toward the open mouth in acute angle relationship to the axis of the bore. The longitudinal axes of the projections are at least 0.01 inch long. The average thickness of each of the flexible projections is less than the length of its longitudinal axis.
