Construction & Design

The gasket’s multi-layer steel design combines durability with flexibility, ensuring a tight, reliable seal under extreme combustion pressures and thermal cycling. Stainless steel layers provide structural integrity and corrosion resistance, while the embossed outer layers coated with Viton rubber enhance sealing against the cylinder head and block surfaces.

Viton, a high-performance fluoroelastomer, is selected for its exceptional heat resistance and chemical stability, making it ideal for the harsh environment inside the combustion chamber. The gasket’s 0.036-inch compressed thickness balances sealing capability with the necessary compliance to accommodate slight variations in engine block and head surfaces, ensuring long-lasting performance.
