Construction & Design

The Cometic MLS-5 Head Gasket features a multi-layer steel (MLS) design consisting of three to five layers of premium stainless steel. Stainless steel is selected for its high tensile strength, excellent rebound properties, and resistance to corrosion, all critical factors for maintaining a reliable seal under extreme engine conditions.

The gasket’s embossed outer layers are coated on both sides with Viton rubber, a synthetic fluoropolymer known for its outstanding heat resistance and chemical stability. This coating allows the gasket to endure temperatures up to 250°C (482°F), making it ideal for high-performance and high-temperature applications.

Each gasket is precision-engineered to the exact bore size of 4.185 inches, ensuring a perfect fit and optimal sealing surface contact. This meticulous design reduces the risk of head gasket failure and enhances overall engine reliability.
