{"product_id":"comp-cams-505-12","title":"COMP Cams Valve Seals 3\/8in Metal W\/PTFE","description":"\u003cp\u003eCOMP 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.\u003c\/p\u003e\u003cp\u003eGenuine COMP Cams.
