Product Details
This is a Multi-Layer Steel (MLS) cylinder head gasket from Cometic, specifically made for the 1275cc A-Series engine found in the 1964-1969 Austin Mini Cooper. It has a 73mm bore and a thickness of .066 inches, designed to seal the combustion chamber and coolant passages between the cylinder head and the engine block.
MLS gaskets are well-built for modern engine demands, offering improved sealing compared to older composite types. The embossed outer layers are coated with Viton, a high-performance fluoroelastomer that helps create a solid seal against combustion pressures and fluids, even under heat. This construction is key to preventing leaks and maintaining proper engine compression.
