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.
Claims4
A tubular sealing member defining a bore and an open mouth, and further defining a plurality of spaced, annular sealing members in said bore to grip a tube to be sealed, the improvement comprising:
- a plurality of said spaced, annular sealing rings defining, in cross section, flexible, elongated projections which, in turn, define longitudinal axes which incline toward said open mouth in acute angle relationship to the axis of said bore, the longitudinal axes of said projections being at least 0.01 inch long, the average thickness of each said projection being less than the length of its longitudinal axis, the inner diameter of said bore between the open mouth and the sealing ring nearest to said open mouth being greater than the inner diameter of said bore between consecutively inwardly positioned sealing rings and the inner diameter of the bore between consecutive sealing rings decreasing in value in the direction inwardly of said sealing member from said open mouth.
