Description
These gaskets feature a multi-layer stainless steel (MLS) construction with embossed, Viton-coated outers for enhanced strength, rebound, and corrosion resistance. The integrated MLX stopper layer strategically focuses clamp load around the cylinders without increasing bore distortion. With an 89.5 mm bore and .042 inch thickness, they are suited for common FA20 setups. The Viton material is heat resistant up to 250°C (482°F), making them suitable for harsh conditions and varied surface finishes.
