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\u003eTypically requiring no machine work, our 504 umbrella seals are a great option for stock guide applications with 3\/8\" valves needing a seal replacement.\u003c\/p\u003e\u003cp\u003eThis product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.\u003c\/p\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":51783851606328,"sku":"C007 504-12","price":33.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-426224-4767746-square_58a433e7-60cb-4426-990b-aeecfdabeb83.webp?v=1778287405","url":"https:\/\/store.motormia.co\/products\/comp-cams-valve-seals-3-8in-umbrella","provider":"MOTORMIA","version":"1.0","type":"link"}
