COMP Cams Valve Seals 11/32in Stem

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. Providing the best sealing properties and spring clearance, viton valve seals are an excellent choice in performance applications. The 506 seals have a .610" OD and fit applications with 11/32" valves and .494" OD guides. Available individually under 506-1 Engines w/ 0.494" OD Valve Guides and 11/32" Valve Stems
