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\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSeal Outer Diameter\u003c\/strong\u003e: \u003cspan\u003e0.6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eValve Guide Outer Diameter\u003c\/strong\u003e: \u003cspan\u003e0.5\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eValve Seal Type\u003c\/strong\u003e: \u003cspan\u003eSteel Jacketed Viton\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eValve Stem Outer Diameter\u003c\/strong\u003e: \u003cspan\u003e8\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eAmazon ASIN\u003c\/strong\u003e: \u003cspan\u003eB0014F1HSE\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eC.A.R.B.
