517-8 - Valve Seals, Metal Body Viton 11/32X.500.

COMP Cams offers a complete line of valve stem oil seals, from the stock GM o-ring to the positive-stop PTFE seal. These seals are a must to keep unwanted oil form entering the combustion chamber through the clearance in the valve guides. The o-ring seals use the standard retainer and oil splash shield. The umbrella seal is normally used when a larger than stock diameter spring is used, and in the case of a double spring, the positive-stop PTFE seal is used. Small diameter Viton seals are also available for triple spring applications.

Some parts are not legal for use in California or other states with similar laws/regulations
