ABSTRACT:
A seal for preventing leakage of pressurized fluid along a flow path along an engagement plane between a first and second members. The seal has a cylindrical body with a first elastomeric ring located on an end and a second elastomeric ring located on a peripheral surface of the cylindrical body. The cylindrical body is located in a passage in the second member. A spring urges the first elastomeric ring into engagement with a face on the first member when the first and second members are joined together. Pressurized fluid which flows from a passage in the first member into the second passage in the second member acts on the cylindrical body to further urge the end into engagement with the first member to prevent fluid leakage along the engagement plane there between.
