Abstract
A seal assembly (10) comprising a sealing body (40), a shoe (42), a first collar (44), and a second collar (46). The shoe (42) is positioned within a space defined by radially inner surfaces of the sealing body (40), the first collar (44) is positioned on a first axial side of the sealing body (40), and the second collar (46) is positioned on a second axial side of the sealing body (40). These components (40, 42, 44, 46) collectively form inter-component sealing surfaces, pocket sealing surfaces, gate sealing surfaces and/or part sealing surfaces which prevent the infiltration of outside fluid into, and the escape of operative fluid from, a fluid coupling.
