Cometic Multi-Layer Steel gaskets are comprised of multiple embossed layers of both proprietary high temperature coated and uncoated stainless steel, requiring less clamp load, creating less bore distortion, and conforms load distribution across the sealing area.
An additional HP Shim Layer can be added to provide increased stress around the combustion seal. Proprietary high temperature coatings along with embossments provide a micro seal for fluids against the head and block surface.
