Construction & Design:

This head gasket features a sophisticated multi-layer steel design, combining multiple embossed stainless steel layers for maximum strength and flexibility. The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for its exceptional heat and chemical resistance, ensuring a reliable seal under harsh operating conditions. The embossed pattern enhances the gasket’s ability to conform to surface irregularities, preventing leaks and maintaining compression.

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 the mechanical forces between dissimilar metals such as aluminum heads and cast iron blocks.
