The Cometic MLS head gasket for the Peugeot XU10J4RS (88mm bore, .040" compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces to provide a high-capacity seal without sealants. MLS construction resists corrosion, rebounds under load, and suits aluminum-to-aluminum or aluminum-to-iron head/block combinations in high-output engines and demanding sealing environments.
