{"product_id":"cca-valve-seal-kits-18","title":"COMP Cams 511-16 - Set of 16 Steel Viton Valve Seals for .500\" Guide Size, 8mm Valve Stem","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\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmazon ASIN:\u003c\/strong\u003e B0014F1HSE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.A.R.B.
