Abstract

A gasket having an upper surface, a substantially cylindrical inner surface abutting the upper surface, a lower surface abutting the inner surface, and generally opposite the upper surface, and an outer surface abutting the upper surface and the lower surface, and generally opposite the inner surface. The outer surface has a sealing surface between the upper surface and the lower surface, a first depression between the sealing surface and the upper surface, and a second depression between the sealing surface and the lower surface. A distance between the first depression and the second depression may be less than a distance between the upper surface and the lower surface. The outer surface may have a first seal wing between the sealing surface and the upper surface, and a second seal wing between the sealing surface and the lower surface.
