The Cometic MLS cylinder head gasket for Peugeot XU9J4, XU9J4Z and XU10J2/XU10J4 engines (86.5mm bore, .045in compressed thickness) uses three to five stainless-steel layers with embossed outer faces coated in Viton rubber. Viton resists heat up to 250°C (482°F). The uncoated stainless shim layer can be varied for thickness requirements, reducing clamp load, limiting bore distortion and improving load distribution for reliable sealing.
