They 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.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44581067751735,"sku":"CO515-16","price":77.15,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/61858.jpg?v=1780477049","url":"https:\/\/enginemaster.com.au\/products\/valve-stem-oil-seals-metal-body-viton-seal-suit-3-8-valve-500-guide-675-o-d-co515-16","provider":"Engine Master","version":"1.0","type":"link"}
