Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring a Viton rubber coating on the outer layers. When compressed, it measures .098 inches thick and is designed for a 100mm bore, specifically for the right-hand side (RHS) of your Porsche 928. MLS gaskets are ideal for sealing between aluminum heads and either aluminum or cast iron blocks, as they can handle the shearing forces that arise from these material combinations.
The strength of these MLS gaskets comes from their layered stainless steel construction, which also allows them to rebound and resist corrosion. The Viton coating on both sides is a heat-resistant synthetic rubber material that can handle temperatures up to 482°F, making it suitable for harsh sealing environments and various load conditions. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements, like the .080 inch thickness of this particular gasket.
