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. |
