COMP Cams Valve Seals 11/32in O Ring

COMP Cams offers a complete line of valve stem Seals, from the stock GM "O-Ring" to the positive-stop PTFE Seal. These Seals are a must to keep unwanted oil from 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, in the case of a double spring, the positive-stop PTFE Seal is used. We also have a smaller diameter Viton Seal available for triple spring Applications. 11/32 O-ring-1 Available individually under 501-1, in a set of 12 under 501-12, in a set of 16 under 501-16 Engines with stock/unmodified valve guides and 11/32" Valve Stems
