COMP Cams 505-16 3/8 Valve Seals PTFE Positive Stop .530 Guides Teflon
Most people are familiar with Comp Cams as one of the premiere performance camshaft manufacturers. However, Comp Cams produces top-quality components for every aspect of your engine's valve train components, with race-proven results for top racing teams from the NHRA, NASCAR, and more. COMP Cams offers a complete line of valve seals, from the stock GM O-rings to the positive-stop PTFE seals. 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. Requires machining the top of the valve guide with a special .530 in. diameter cutter.
