Abstract
A sealing device is provided for use with an assembly having radially inner and outer parts in fluid communication and movable relative to one another. The sealing device includes a first annular lip which defines an opening for receiving the radially inner part, and an annular channel disposed radially outward of the opening. The first annular lip is configured and adapted for deformation and compressive sealed engagement with the radially inner part while permitting movement of the radially inner part relative thereto. An annular body integrally formed with the first annular lip of the sealing device defines an interior space in communication with the annular channel and the opening. The annular body extends radially outward of the first annular lip and is configured and adapted for sealed engagement with the radially outer part.
