3/8 Valve Stem Seals Umbrella Type

The 3/8 Valve Stem Seals Umbrella Type from COMP CAMS provide an essential solution for engine builders looking to maintain optimal oil control within the cylinder head. These seals are designed to prevent excess oil from traveling down the valve stem and entering the combustion chamber, which helps reduce blue exhaust smoke and carbon buildup. For those performing a top-end refresh or a complete engine overhaul, choosing reliable seals is a critical step in ensuring long-term performance and efficiency. You can buy these as a complete set to ensure uniform sealing across all intake and exhaust valves during your next project.

Manufactured from high-quality rubber, these 3/8 Valve Stem Seals Umbrella Type are engineered to withstand the rigorous heat and chemical exposure found in high-performance internal combustion engines. The umbrella design works by moving with the valve stem, effectively shielding the guide from excessive oil splash without requiring the machining of the cylinder head guides. This specific set is designed for 3/8-inch valve stems and fits securely over stock-diameter guides to provide a consistent and durable barrier. The material flexibility ensures a tight fit that accommodates the rapid reciprocating motion of the valve train during high-RPM operation.

These 3/8 Valve Stem Seals Umbrella Type are ideal for street-performance applications and classic engine restorations where stock guide diameters are maintained. This set of 16 ensures you have enough components for a standard V8 engine configuration, making it a convenient choice for most domestic performance builds. Whether you are reviewing your current oil consumption or assembling a new valvetrain, these specifications meet the requirements for a wide variety of overhead valve engines. Installation is straightforward and requires no special machining, providing a cost-effective way to improve engine longevity and maintain cleaner emissions.
