Abstract
A bushing and sealing ring assembly including a sealing ring and a bushing. The sealing ring has a cylindrical base with an external thread and a reduced diameter, upstanding cylindrical sleeve extending co-axially from one end of the base with a predetermined height, an upper outer edge and an upper inner edge. The base and the sleeve are provided with a circular central aperture for receiving and retaining a first cylindrical member. The bushing has a cylindrical depending sidewall with an internal thread and a circular central aperture for receiving the sealing ring and a second cylindrical member and a top plate extending transversely partially inwardly into the central aperture to sealingly receive the upper outer edge of the sealing ring and having a predetermined thickness. The sealing ring is threadably retainable within the cylindrical sidewall abutting the top plate of the bushing to preassemble the sealing ring with respect to the bushing, the predetermined height of the sleeve is greater than the predetermined thickness of the top plate such that the upper outer edge and the upper inner edge of the sleeve protrude beyond the bushing. The sleeve is adapted to engage the …
