Cometic BMC 1.8L B-Series .051in MLS Cylinder Head Gasket - 83mm Bore

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.051". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. BMC 1.8L B-Series .051in. MLS Cylinder Head Gasket; 83mm Bore MGB 1975-1980 1.8L 18G/18GA

• The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes
• The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements
• Requires less clamp load creating less bore distortion
• Conforms load distribution across the sealing area
• Embossed Outer Layers Coated w/Viton

The Cometic Gasket BMC 1.8L B-Series .051 inch MLS Cylinder Head Gasket is engineered for high-performance engines, offering superior sealing and durability. Crafted from multiple embossed layers of stainless steel with outer layers coated in Viton rubber, this gasket provides excellent resistance to harsh sealing environments. The compressed operating thickness is just 0.051 inches, ensuring a tight seal that minimizes bore distortion and supports optimal engine performance. Designed specifically for MG MGB models from 1963 to 1974, including 1965, 1966, 1969, 1970, 1971, 1972, 1973, and 1974, this gasket is ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. The multilayer steel construction withstands shearing forces created by different materials and offers increased strength, rebound capability, and corrosion resistance. The embossed outer layers are coated on both sides with Viton, a heat-resistant elastomer capable of withstanding temperatures up to 482°F, making it suitable for demanding engine applications. The uncoated stainless steel center or shim layer can be customized to meet various thickness requirements, providing flexibility for different engine rebuild needs. This gasket promotes even load distribution across the sealing area, reducing the need for excessive clamp load and helping prevent bore distortion, ultimately supporting reliable engine operation. It requires no sealants, simplifying installation and ensuring a clean, effective seal for high-output engine applications. Whether you're restoring or enhancing a vintage MG MGB, this MLS gasket ensures a durable, high-performance seal compatible with your specific engine build.
