{"product_id":"comp-cams-valve-seals-5-16in-ptfe-1","title":"COMP Cams Valve Seals 5\/16in PTFE","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":52736098533696,"sku":"CCA500-12","price":58.99,"currency_code":"USD","in_stock":false}],"url":"https:\/\/velocityracewerks.com\/products\/comp-cams-valve-seals-5-16in-ptfe-1","provider":"Velocity Race Werks","version":"1.0","type":"link"}
