Construction & Design

The gasket is constructed from multiple embossed layers of stainless steel, providing exceptional strength and flexibility. The outer layers feature a Viton rubber coating, a high-performance elastomer known for its resistance to heat, oils, and chemicals, making it ideal for harsh sealing environments. This coating enhances the gasket’s ability to maintain a tight seal under varying load conditions and surface finishes.

The center shim layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design enables the gasket to rebound and maintain sealing integrity despite thermal cycling and mechanical stresses common in high-performance engines.
