{"product_id":"comp-cams-valve-seals-5-16in-ptfe-w-500","title":"COMP Cams Valve Seals 5\/16in PTFE W\/.500","description":"COMP Cams offers a complete line of valve stem Seals, from the stock GM \"O-Ring\" to the positive-stop PTFE Seal. 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.","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":51465187787048,"sku":"CCA513-12","price":32.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/0218\/1416\/files\/ac9e1d4f-6cfb-4128-87f8-4516d8568b57-800_8ed19eda-93d8-48ac-bd77-cd05b7f71a0e.jpg?v=1771987982","url":"https:\/\/shop.paradigm-automotive.com\/products\/comp-cams-valve-seals-5-16in-ptfe-w-500","provider":"Paradigm Automotive \u0026 Performance Shop","version":"1.0","type":"link"}
