Cometic MLS head gaskets for Mazda FS-DE/FS-DET engines specify an 84mm bore and a compressed operating thickness of 0.075". These multi-layer steel gaskets use embossed outer stainless layers coated with Viton and an uncoated stainless center shim layer; the construction is intended to provide strong sealing across varying load conditions without requiring sealants. Cometic notes MLS gaskets suit aluminum-to-aluminum and aluminum-to-cast-iron interfaces and offer rebound and corrosion resistance.
