The Cometic MLX cylinder head gasket for Cummins 5.9L 6BT engines is a .061" multi-layer stopper-style gasket with a 4.100" bore, engineered to improve combustion sealing without increasing bore distortion. MLX gaskets incorporate an integrated stopper layer to enhance clamp load distribution around the cylinder. This design typically requires no added sealants or re-torque and is offered to provide reliable sealing in demanding diesel applications.
