ABSTRACT:
A neoprene boot fixes a static race of a rotary shaft seal within a housing bore. An annular rotating race bears a carbon insert laterally mated to the radial face of the static race. A bushing borne by the rotating shaft supports a neoprene seal sleeve of inverted T-shape configuration including a flexible lip reinforced with a steel ring which is pressed by distortion and fluid pressure against a rotating sleeve, to which the sleeve base is locked. The rotating race presses against the static race to maintain a high integrity fluid tight seal between the rotating shaft and the fixed housing.
