3/8 Valve Stem Seals Umbrella Type

The 3/8 Valve Stem Seals Umbrella Type from COMP CAMS is an essential component for engine builders aiming to optimize oil control within the cylinder head. These seals effectively prevent excess oil from traveling down the valve stem and entering the combustion chamber, thereby reducing blue exhaust smoke and carbon buildup. They are particularly useful for those undertaking a top-end refresh or a complete engine overhaul.

Manufactured from high-quality rubber, these 3/8 Valve Stem Seals Umbrella Type are designed to endure the intense heat and chemical exposure typical in high-performance internal combustion engines. The umbrella design allows the seals to move with the valve stem, effectively shielding the guide from excessive oil splash without necessitating machining of the cylinder head guides. This ensures a reliable and durable barrier against oil leakage.

Ideal for street-performance applications and classic engine restorations, this set of 16 seals ensures uniform sealing across all intake and exhaust valves. The seals are specifically designed for 3/8-inch valve stems and fit securely over stock-diameter guides, accommodating the rapid reciprocating motion of the valve train during high-RPM operation. This makes them a critical choice for maintaining engine performance and efficiency.
