Cometic MLS Head Gaskets

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Cometic Carburetor Power Valve Gaskets

Cometic carburetor power valve gaskets are manufactured from a high performance-inspired compressible fiber that seals tight the first time. This highly durable material is compatible with a wide assortment of fuels and additives (and resist swelling). The gaskets are precision die-cut to ensure a perfect fit every time. They provide torque retention, crush resistance, and sheer strength—and seal using low clamp force while releasing easily. The gasket material will not stick to the carburetor or intake manifold and can be reused. These mounting seals are available for a wide range of carburetor models and styles, including carbs from Holley, Barry Grant, and Quick Fuel. Order the gasket recommended for your application.

Cometic Gasket Piston Jet Cooler Gaskets

Cometic Gasket piston jet cooler gaskets (or piston cooling jets) enhance engine performance and longevity by preventing overheating, reducing the risk of piston seizure, and allowing for higher thermal loads, especially during performance builds. PCJs are particularly beneficial for the Harley-Davidson® Milwaukee Eight (M8) engines, which are known for their high compression and potential for overheating. By keeping pistons cooler, PCJs allow for higher compression ratios and more aggressive tuning, leading to increased horsepower and torque. Reduced piston temps also translate to less wear and tear on the engine and reduces risk of future costly repairs.
