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 seals are normally used when a larger-than-stock diameter spring is used. In the case of a double spring, the positive stop PTFE seals are used. For triple-spring applications, use the smaller-diameter Viton® seals.    \u003cdiv\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003eValve Stem Diameter:0.313 in.    \u003cdiv\u003eValve Stem Seal Type:Positive stop\u003c\/div\u003e     \u003cdiv\u003eValve Stem Seal Material:PTFE\u003c\/div\u003e     \u003cdiv\u003eMachine Work Required:Yes\u003c\/div\u003e     \u003cdiv\u003eValve Guide Diameter (in):0.500 in.\u003c\/div\u003e     \u003cdiv\u003eValve Stem Seal Outside Diameter (in):0.600 in.\u003c\/div\u003e     \u003cdiv\u003eQuantity:Sold as a set of 16.\u003c\/div\u003e    Notes:Requires machining the top of the valve guide with a special .500 in. diameter cutter.\u003c\/div\u003e    \u003c\/td\u003e   \u003c\/tr\u003e  \u003c\/tbody\u003e \u003c\/table\u003e  \u003cp\u003e\u003cbr\u003e .\u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44552367702327,"sku":"CO513-16","price":99.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/61853.jpg?v=1780498321","url":"https:\/\/enginemaster.com.au\/products\/comp-cams-valve-stem-seals-co513-16-500-guide-size-5-16-valve-600-o-d","provider":"Engine Master","version":"1.0","type":"link"}
