Cometic MLS head gaskets use multiple embossed layers of AMP coating and uncoated stainless steel to meet demanding sealing environments. The outer embossed layers conform to varied surface finishes while a central uncoated shim layer lets thickness be tailored. These MLS gaskets require less clamp load to reduce bore distortion and help distribute sealing loads across the combustion area for reliable sealing under varied conditions.
