Construction & Design

The Cometic MLS Head Gasket is constructed from multiple layers of high-grade stainless steel, providing exceptional tensile strength and flexibility to withstand engine stresses. The embossed outer layers are coated on both sides with Viton rubber, a synthetic fluoropolymer elastomer known for its outstanding heat resistance and chemical stability. This coating enhances the gasket’s ability to seal combustion gases, coolant, and oil, even under extreme temperature fluctuations and pressure cycles.

The multi-layer design compensates for surface irregularities and engine block/head movement during operation, ensuring a consistent and reliable seal. This reduces the risk of head gasket failure and makes the gasket suitable for both OEM replacement and performance upgrades.
