Construction & Design

The Cometic MLS Head Gasket features a sophisticated multi-layer steel design, combining multiple embossed stainless steel layers to provide exceptional strength and flexibility. The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for its excellent resistance to heat, oil, and chemicals, ensuring a reliable seal even under extreme thermal cycling. The gasket’s 0.066" compressed thickness is engineered to maintain consistent sealing pressure, accommodating the natural expansion and contraction of engine components. This design effectively manages the mechanical stresses between aluminum cylinder heads and either aluminum or cast iron engine blocks, preventing leaks and maintaining optimal engine performance.
