An improved seal assembly utilizing a cup gasket having a flange portion secured or sandwiched between side surface of a mating ring and an inner surface of a radially extending side portion of an inner sleeve such that a static seal occurs in an axial direction. The seal further including a gap between an inner circumferential surface of the mating ring and the outer circumferential surface of the inner sleeve to detect any leakage past the static seal. Such a seal assures a long-term sealed mounting of the mating ring regardless of elastomer compressions set, shrinkage, or thermal contraction.
