Description

Part #: 502-12

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.

Typically requiring no machine work, our 502 umbrella seals are a great option for stock guide applications with 11/32" valves needing a seal replacement.

This product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
