Construction & Design

The Cometic MLS gasket features a robust multi-layer steel design that combines three to five layers of stainless steel to provide outstanding strength, flexibility, and heat resistance. Stainless steel is selected for its ability to withstand extreme temperatures, resist corrosion, and maintain its shape under high pressure, ensuring a long-lasting seal.

Embossed outer layers create a controlled deformation that improves sealing by conforming to surface imperfections on the cylinder head and block. Both sides of the gasket are coated with a durable Viton rubber compound, known for its excellent heat resistance and chemical durability, which prevents leaks of coolant, oil, and combustion gases even in harsh engine environments.

The gasket thickness of 0.140 inches is optimized specifically for the Chrysler 6.1L Gen-3 Hemi engine, ensuring proper compression and combustion chamber sealing for peak engine performance.
