Construction & Design:

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

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