ABSTRACT:
A mechanical end face seal assembly with first and second, relatively rigid, primary seal rings of a generally T-shaped cross-section and a pair of annular secondary elastomeric seal rings. The secondary rings provide a combination of radial compressive load and axial end face load and are of generally parallelogram shaped cross-section. One secondary seal member extends radially outwardly from its associated primary seal ring and the other secondary ring extends radially inwardly from its associated primary ring.
