• Designed to withstand shearing forces between dissimilar metals, preventing gasket failure
• Coated on both sides to enhance sealing capability and durability over time

Construction & Design

This MLS gasket features multiple embossed layers of high-grade stainless steel, providing the structural integrity necessary for high-performance and high-stress engine applications. The outer layers are coated with Viton, a fluorocarbon elastomer renowned for its excellent heat resistance and chemical stability, ensuring a dependable seal even under extreme operating conditions.

The center shim layer is made of uncoated stainless steel, allowing for precise thickness adjustments to match the engine’s exact specifications. This multi-layer design enables the gasket to flex and rebound as the engine components expand and contract during operation, effectively preventing leaks of coolant, oil, and combustion gases. This advanced engineering contributes directly to engine longevity and consistent performance.
