ABSTRACT:
A sealing ring for sealing against fluid leakage between mainly planar surfaces of a pair of parts that are mounted in forced relation against each other. The ring comprises, in an exemplary form, a resilient member having a radially oriented annular section, and first and second ends projecting generally in opposite axial directions, respectively, from radially inner and radially outer portions of the annular section. The first end includes a first member projecting generally axially from the annular section, a second member projecting generally radially outwardly from the first member, and a third member projecting generally axially towards the annular member, such that the first, second and third members collectively have a generally U-shaped cross-section. Radially outer surfaces of the first end and of the third member of the second end comprise sealing surfaces; and a pair of axially opposite surfaces of the annular section comprises generally parallel surfaces for sealing against the pair of parts that are mounted in a forced relation against each other.
