Construction & Design:

The Cometic MLS gasket features a sophisticated multi-layer steel design, combining three to five layers of high-grade stainless steel. This construction provides exceptional strength and flexibility, allowing the gasket to rebound after compression and maintain a tight seal. The embossed outer layers enhance sealing by conforming to surface irregularities on the cylinder head and engine block.

Both sides of the gasket are coated with Viton rubber, a synthetic fluoropolymer known for its outstanding heat resistance and chemical stability. This coating protects the gasket from corrosion and degradation caused by exposure to engine fluids and extreme temperatures, ensuring long-lasting performance.
