ABSTRACT:
An annular ring having a sealing lip and having two or more annular beads, is installed in a groove. Interacting dimensions of ring and groove are such that the height of one bead added to the thickness of the ring is less than the width of the groove while the height of two opposed beads together plus the thickness of the ring is greater than the width of the groove. The annular beads are formed on the ring such that the ring must deform in order to fit into the groove. Deformation of the ring is accompanied by an angular displacement of the sealing lip so as to form a positive seal.
