Viton Valve Seals - 5/16 Steel Body .500

The Viton Valve Seals - 5/16 Steel Body .500 from COMP CAMS are essential internal engine components designed to prevent oil leakage past valve stems and maintain proper combustion chamber sealing during high-rpm operation. These seals are crucial for anyone rebuilding a stock engine, upgrading a performance build, or restoring a classic muscle car, ensuring longevity and reliability.

Featuring a robust steel body construction paired with a Viton elastomer lip design, these valve seals offer superior heat resistance and chemical compatibility compared to standard rubber seals. The 5/16-inch stem size and .500-inch body diameter make these seals suitable for various engine applications, while the steel reinforced body prevents extrusion under vacuum and pressure cycling, maintaining sealing integrity across thousands of heat cycles.

Engine builders, performance enthusiasts, and mechanics tackling cylinder head service will find these valve seals beneficial. They are particularly useful in high-performance applications where maintaining oil control to the valve train is critical.
