Construction & Design

The MLS-5 Head Gasket features a multi-layer steel design, combining three to five layers of stainless steel to provide exceptional strength, flexibility, and resistance to thermal cycling. Stainless steel is selected for its corrosion resistance and ability to maintain structural integrity under mechanical stress.

Both sides of the gasket’s embossed outer layers are coated with Viton rubber, a high-performance fluorocarbon elastomer known for its excellent heat resistance and chemical stability. This coating enhances sealing by conforming to surface imperfections, effectively preventing leaks caused by combustion gases or coolant. The gasket thickness of 0.051 inches ensures proper compression and fitment within the cylinder head assembly, maintaining optimal engine performance and reliability.
