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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eSeal Outer Diameter: 0.63 IN\n\u003c\/li\u003e\u003cli\u003eValve Guide Outer Diameter: 0.53 IN\n\u003c\/li\u003e\u003cli\u003eValve Seal Type: Positive Stop PTFE\n\u003c\/li\u003e\u003cli\u003eValve Stem Outer Diameter: 11\/32 IN\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eEngine Valve Stem Oil Seal Set\u003c\/li\u003e","brand":"Comp Cams","offers":[{"title":"Default Title","offer_id":52886001287531,"sku":"CCA-503-12","price":38.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/CCA-503-12-1.jpg?v=1770605862","url":"https:\/\/caautoparts.com\/products\/engine-valve-stem-oil-seal-cca503-12","provider":"CA Auto Parts","version":"1.0","type":"link"}
