About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket, designed to seal the combustion chamber between the cylinder head and engine block. It features a 90mm bore and a compressed thickness of .120 inches, making it suitable for a range of vehicles including the Nissan 240SX, Frontier, and Xterra, as well as classic Jaguar XK models. MLS gaskets are built for high-output engines and don't require sealants, offering a strong, reliable seal.

Cometic constructs these gaskets from multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that handles demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness control. This construction helps these gaskets withstand the forces created when mating different block and head materials, like aluminum to cast iron.
