A sealing ring having a predetermined axis of symmetry is formed of a resiliently compressible elastomer for use in a sealing ring system in which two members are secured together with the ring interposed therebetween. The sealing ring has an annular base portion that has substantially parallel first and second axially extending surfaces with each surface having a first axial edge and a second axial edge spaced therefrom, and the second axial edges are joined by a radially extending surface. Integrally formed with the base portion is an annular head portion that extends between both of the first axial edges of the axially extending surfaces of the base portion. The head portion has a predetermined maximum axial thickness and at least one substantially planar surface extending generally radially a predetermined distance from the first axial edge of at least one of the axially extending surfaces of the base, whereby each of the planar surfaces and the adjacent axially extending surfaces form a shoulder.
