Cometic Nissan Silvia / 240SX 90mm .051 inch MLS Head Gasket KA24DE 1990-UP

This Multi-Layer Steel (MLS) head gasket from Cometic is built with multiple embossed layers of stainless steel, featuring outer layers coated with Viton rubber. The compressed operating thickness comes in at 0.051 inches, making it a solid choice for sealing your Nissan's cylinder head. MLS gaskets are ideal for pairing aluminum heads with either aluminum or cast iron blocks because they can handle the shearing forces that arise from the different materials expanding and contracting.

The strength of these gaskets comes from their layered stainless steel construction, which also helps them rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant material, capable of handling temperatures up to 482 degrees Fahrenheit, and it's designed to perform well in tough sealing environments. The center layer is stainless steel and can be varied to achieve different thickness requirements, like the 0.051 inch specification on this particular gasket. Because they are designed for high-output engines and use advanced materials, these MLS gaskets typically do not require any additional sealants.
