Construction & Design

This MLS head gasket features a sophisticated multi-layer steel construction that balances strength with flexibility. The gasket’s outer layers are embossed stainless steel coated with Viton, a high-performance rubber compound known for its excellent heat resistance and chemical durability. The center shim layer is uncoated stainless steel, allowing for precise thickness control to meet exact engine requirements.

The design accommodates the different expansion rates between aluminum cylinder heads and either aluminum or cast iron engine blocks, preventing gasket failure caused by shearing forces. This robust construction ensures a reliable seal that maintains compression and prevents coolant or oil leaks, even under extreme operating conditions.
