ABSTRACT:
A floating annular sealing ring having a plastic coated surface is adapted to be received by an annular groove defined by a bushing and shaft sleeve mounted upon a rotating shaft to provide an effective liquid and gas seal. The encapsulated deformable annular seal may include a circular, an oval, a lobed, a rectangular, a square or triangular cross-section, which cross-section is capable of conforming to the inside surface of the bushing sleeve and the outside surface of the shaft when the sleeve is moved axially towards the bushing to thereby deform the encapsulated floating annular seal to provide a mechanical seal between the rotating shaft, sleeve and bushing.
