Product Details
If you're working on the engine of your 1967-1974 MG Midget, this Cometic BMC 1275 A-Series cylinder head gasket is a solid choice for ensuring a proper seal. It's specifically made for the A-Series engine with a 73mm bore and a compressed thickness of .040 inches.
This gasket is a Multi-Layer Steel (MLS) design, which means it's built from several layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it suitable for high-output engines. MLS gaskets don't require any additional sealants and work well with both aluminum and cast iron engine blocks.
