Construction & Design

The Cometic MLS gasket features a robust multi-layer steel design that combines multiple layers of high-grade stainless steel for superior tensile strength and flexibility. This construction allows the gasket to maintain a tight, leak-proof seal even under extreme thermal cycling and high combustion pressures typical of the 5.7L Gen-3 Hemi engine.

Each outer steel layer is embossed to enhance sealing capability and coated with Viton rubber, a synthetic elastomer known for its excellent resistance to heat, chemicals, and oil. This coating ensures a secure seal against the cylinder head and engine block surfaces, preventing leaks and improving overall engine reliability.
