Product Details
Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) cylinder head gasket is a prime example. If you're working on the A-Series engine in your 1967-1974 MG Midget, Austin Mini Cooper, or MG 1300, this gasket is designed to handle the job. It's built with multiple layers of stainless steel, which gives it strength and helps it resist corrosion and shearing forces, especially important when mating aluminum heads to cast iron blocks.
What really sets this gasket apart is the Viton rubber coating on the outer stainless steel layers. Viton is a heat-resistant material that can handle temperatures up to 482°F (250°C), making it ideal for sealing in demanding engine environments. This coating, combined with the embossed layers, means you don't need to use any extra sealants during installation. The center layer is stainless steel and can be varied to achieve different thicknesses; in this case, it's set up for a compressed operating thickness of 0.098 inches with a 73mm bore, ensuring a solid seal for your engine.
