Construction & Design

This head gasket features a sophisticated multi-layer steel design, combining multiple embossed stainless steel layers to maximize strength and flexibility. The embossed pattern enhances the gasket’s ability to conform to surface irregularities, preventing leaks and maintaining compression under extreme conditions.

The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for exceptional heat and chemical resistance, ensuring a reliable seal even in harsh operating environments. The uncoated stainless steel center shim layer provides structural integrity and can be varied in thickness to accommodate specific engine requirements.

This design allows the gasket to absorb and rebound from the stresses caused by thermal expansion and contraction, as well as mechanical forces between dissimilar metals such as aluminum heads and cast iron blocks, ensuring long-term durability and performance.
