Cometic BMC 1275 A-Series .036in MLS Cylinder Head Gasket - 73mm Bore

This Multi-Layer Steel (MLS) head gasket from Cometic is built with a compressed operating thickness of 0.036 inches and a 73mm bore, specifically for the 1964-1969 Austin Mini Cooper. MLS gaskets are well-suited for high-output engines because they are made from multiple layers of stainless steel, which gives them increased strength and the ability to rebound while resisting corrosion. This construction also helps them handle the shearing forces that can occur between different block and head materials, making them a solid choice for both aluminum-to-aluminum and aluminum-to-cast iron setups.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material rated up to 482 degrees Fahrenheit. Viton is known for its ability to handle tough sealing environments, varying load conditions, and different surface finishes. The center layer is uncoated stainless steel, and its thickness can be adjusted to meet various requirements, like the 0.036 inch compressed thickness specified for this application. Because they are designed for maximum sealing performance, these MLS gaskets typically do not require any additional sealants.
