Construction & Design

The Cometic MLS gasket features a robust multi-layer steel design that combines strength and flexibility to maintain a tight seal under extreme thermal cycling and high combustion pressures. Premium stainless steel layers allow the gasket to rebound and adapt to surface irregularities, ensuring consistent sealing performance.

Its embossed outer layers are coated with Viton rubber, a high-performance elastomer known for exceptional resistance to heat, chemicals, and wear. This coating enhances the gasket’s ability to seal against cylinder head and engine block surfaces, minimizing the risk of leaks from coolant, oil, or combustion gases.

Manufactured to precise tolerances, this gasket guarantees a perfect fit and optimal performance in the demanding environment of the 5.7L Gen-3 Hemi engine.
