SBC Water Pump Gasket

The Cometic Gaskets SBC Water Pump Gasket (Part C5299-018) is a precision-engineered sealing component designed for Small Block Chevy water pump applications. Built with an aluminum core and Foamet-rubber facing, this gasket delivers reliable coolant containment and prevents leakage at the water pump mounting surface—a critical seal that protects against overheating and coolant loss during extended operation.

Cometic's aluminum core construction provides superior dimensional stability under thermal cycling, a key advantage in high-performance and street applications where temperature fluctuations stress gasket materials repeatedly. The Foamet-rubber facing compresses uniformly across the water pump flange, ensuring consistent sealing pressure and reducing the risk of edge leakage that can plague inferior gasket designs. This combination enables the gasket to withstand the pressure demands of modern cooling systems while maintaining a precise fit across the entire sealing surface.

This gasket is essential for any Small Block Chevy engine rebuild, water pump replacement, or cooling system maintenance. Whether rebuilding a 350, 327, or 305 engine, technicians and enthusiasts rely on Cometic gaskets to restore original cooling system integrity without risking future leaks. The lightweight design—0.04 lbs—simplifies installation, while the compact dimensions ensure perfect fitment on standard SBC water pump housings. Each gasket is sold individually for single-pump applications or may be purchased in quantity for fleet maintenance or multiple-engine builds.

Cometic Gaskets is recognized in the automotive industry for producing OEM-quality gaskets that exceed typical performance standards. This SBC water pump gasket exemplifies that reputation, offering the durability and precision expected by professional shops and serious hobbyists alike.
