Cometic GM Gen-3/4 Small Block V8 Coolant Bypass Seals

If you're working on a GM Gen-3 or Gen-4 Small Block V8, these coolant bypass seals from Cometic Gasket are what you need to ensure a clean and leak-free cooling system. These seals are made from a soft durometer molded rubber, specifically shaped to fit the sealing surface or cavity precisely. They are designed to match the higher performance demands of modern engines, helping to prevent coolant leaks that can cause overheating and other issues.

Cometic forms this rubber to the exact shape of the sealing area, which helps create a solid seal. For added rigidity and the ability to reuse them if needed during a build, they can be bonded to a steel or plastic carrier, though this specific part number is for the molded rubber seals themselves. They are a well-built component that helps maintain the integrity of your engine's cooling system, especially important when you're pushing the engine's performance limits.

These seals fit a wide range of GM vehicles, including popular models like the Chevrolet Corvette, Cadillac Escalade, and Chevrolet Silverado. Make sure you have these on hand when you're rebuilding or servicing the cooling system on your compatible GM V8.
