Product Details
If you're working on the engine of your 1967-1974 MG Midget or MG 1300, this Cometic BMC 1275 A-Series Multi-Layer Steel (MLS) cylinder head gasket is built to handle the job. It's designed with a 74mm bore and a compressed thickness of .120 inches, making it a solid choice for rebuilding or repairing your A-Series engine.
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 tough sealing environments and various surface finishes, ensuring a strong seal without needing additional sealants. This construction is ideal whether you're mating aluminum heads to an aluminum block or aluminum heads to a cast iron block, as it can manage the shearing forces between different metals.
The center layer is uncoated stainless steel and can be varied to meet different thickness requirements, which is how Cometic achieves the specific .120 inch compressed thickness for this gasket. This well-built gasket is designed to provide reliable sealing for your engine's performance.
