Construction & Design:

The Cometic MLS-5 Head Gasket features a multi-layer steel (MLS) construction consisting of three to five stainless steel layers. Stainless steel is chosen for its high tensile strength, excellent rebound characteristics, and resistance to corrosion, which are critical for maintaining a reliable seal under extreme engine conditions.

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

Each gasket is precision-engineered to match 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 improves overall engine reliability.
