Cometic Toyota Gen-3 3S-GE/3S-GTE .066in MLS Cylinder Head Gasket - 87mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring outer layers coated with Viton rubber. The compressed operating thickness comes in at 0.036 inches, designed to handle the demands of high-output engines without needing additional sealants. MLS gaskets are a solid choice for sealing aluminum heads to either aluminum or cast iron blocks, effectively managing the shearing forces that can arise between dissimilar metals.

The strength of these MLS 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 withstanding temperatures up to 482°F (250°C), making it suitable for harsh sealing environments and various surface finishes. A central, uncoated stainless steel layer allows for adjustments to meet different thickness requirements, like the 0.066-inch specification on this particular gasket for an 87mm bore.
