COMP Cams Valve Seals 3/8 Viton Metal Body

When you're rebuilding the top end of your engine, ensuring proper valve stem sealing is crucial for performance and longevity. These COMP Cams valve seals are designed to keep oil from getting past the valve guides and into the combustion chamber, which can cause smoking, fouled plugs, and reduced power.

These seals feature a durable Viton material, known for its excellent resistance to heat and oil, making them a solid choice for performance applications where engines run hotter. The metal body construction adds rigidity and helps ensure a secure fit onto the valve guide. They are specifically made for 3/8-inch valve stems and valve guides that measure .530 inches in diameter, with an outer diameter of .575 inches. This precise sizing helps provide optimal sealing and clearance for your valve springs.

This set includes eight seals, enough for a typical V8 engine. Proper installation is key to their effectiveness, so be sure to refer to your engine's service manual for the correct procedure.
