We specialize in sealing products for BMW autos and motorcycles.  This o-ring is pressed into the rear output shaft of the engine and is often the culprit for oil leaks in the bell housing as the OEM o-ring deteriorates over time.  Our o-ring is made of FKM (Viton) which holds up far better in the engine environment.
