51616.31 In. x .530 In. Steel Body Viton Valve Seal

offers a complete line of valve seals, from the stock gm o-rings to the positive-stop ptfe seals. 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.
