The Cometic MLS head gasket for the BMC 1275 A‑Series (.140" compressed thickness, 73mm bore) is a high-thickness multi-layer steel gasket with embossed outer layers coated in Viton and an uncoated center shim for thickness control. It’s specified for 73mm bore applications requiring a substantial MLS gasket. The construction spreads clamp load, resists harsh sealing environments and is supplied to function without sealants in typical installations.
