Product Details
If you're working on the engine of your 1967-1974 MG Midget, Austin Mini Cooper (1964-1969), or MG 1300 (1968-1969), this Cometic BMC 1275 A-Series Multi-Layer Steel (MLS) cylinder head gasket is built to handle the job. It's designed to provide a strong seal between your cylinder head and engine block, which is crucial for maintaining compression and preventing coolant and oil leaks.
This gasket uses multiple 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°F (250°C) and works well with different block and head materials, including aluminum and cast iron. The compressed operating thickness is 0.120 inches with a 73mm bore, ensuring it fits your specific A-Series engine configuration. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
