Claim Text:
1. A sealing device for use with an assembly having radially inner and outer parts in fluid communication and movable relative to one another, the sealing device comprising: a first annular lip which defines an opening for receiving the radially inner part, wherein the first annular lip also defines an annular channel disposed radially outward of the opening, the first annular lip configured and adapted for deformation and compressive sealed engagement with the radially inner part while permitting movement of at least one of the radially inner and outer parts relative thereto, wherein the first annular lip curves radially inward from an annular body such that it radially overlaps itself; a second annular lip integrally formed with the annular body, the second annular lip configured and adapted for deformation and compressive sealed engagement with the radially outer part; and the annular body integrally formed with the first annular lip and defining an interior space in communication with the annular channel and the opening, the annular body extending radially outward of the first annular lip via a flange and configured and adapted for sealed engagement with the radially outer part via the flange, wherein the annular body is thicker than the first annular lip and the flange extends radially outward from the annular body; wherein the first and second annular lips extend from opposite sides of the annular body, wherein the first and second annular lips each have a C-shaped cross section which are perpendicular in direction of curvature relative to each other, wherein the first annular lip extends further radially inward than the second annular lip, and wherein the sealing device is formed from one of a metal and a metal alloy.
