Construction & Design

The Cometic MLS gasket features a robust multi-layer steel design, combining three to five layers of stainless steel to provide exceptional strength and resilience. Stainless steel’s natural ability to rebound after compression helps maintain a tight seal even under fluctuating engine pressures and temperatures, reducing the risk of leaks and gasket failure.

Each outer layer is embossed to enhance sealing capability and coated on both sides with premium Viton rubber. This specialized coating resists heat up to 250°C (482°F) and offers excellent chemical resistance, enabling the gasket to withstand harsh sealing environments and aggressive fluids commonly encountered in high-performance engines.
