Construction & Design

The Cometic MLS gasket is expertly crafted using multiple layers of stainless steel, providing superior strength and flexibility compared to traditional composite gaskets. The stainless steel layers are precision-formed and embossed to enhance sealing pressure and conform precisely to cylinder head and block surfaces.

Both sides of the gasket are coated with a Viton rubber compound known for exceptional heat resistance and chemical durability. This coating helps maintain a reliable seal even under extreme temperatures and combustion pressures commonly experienced in high-performance or heavy-duty engines.

By combining these materials and manufacturing techniques, Cometic delivers a gasket that resists corrosion, warping, and blowouts, ensuring consistent engine performance and longevity.
