Abstract
A shaft seal assembly has an elastomer load ring seated in an annular groove provided in an organic plastic sealing ring. The sealing ring is constructed to provide greater unit loading at the outer edges of the sealing surface than at the remainder of the sealing surface. The end faces of the sealing ring are free from contact with adjacent structure.
