Overview

Cometic Exhaust Manifold Gaskets

Cometic exhaust manifold gaskets are high performance automotive seals designed to withstand extreme cylinder pressures and temperatures up to 2,000 degrees F. Engineered primarily from Multi-Layer Steel (MLS) or composite materials, they prevent exhaust leaks by maintaining a tight seal between the engine cylinder head and the exhaust manifold.

Additional details:

* Multi-Layer Steel (MLS): Built with multiple layers of stainless steel, MLS gaskets resist corrosion and will not burn through or push out under high-boost or racing conditions. They also have an outer layer coated with heat-resistant, rubber-based material (like Viton®) to conform to less-than-perfect mating surfaces
* No Sealants Needed: They're designed to be installed dry, requiring no messy, additional sealants during assembly
* Specialized Materials: Depending on the application, Cometic utilizes materials like HTS (High Temperature Steel), Armor Core, and AFM (Aluminum Foam Material) to insulate against heat and ensure a reliable seal even on warped or uneven flanges
* Thermal Expansion Handling: These gaskets are highly effective at managing the shearing forces and expansion that happen when different materials—such as an aluminum cylinder head and a cast-iron exhaust manifold—meet
