Cometic Peugeot XU9J4/XU9J4Z/XU10J2/XU10J4 .120in MLS Cylinder Head Gasket - 84mm Bore

If you're rebuilding the top end of your 1989-1991 Peugeot 405, a solid cylinder head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines.

This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with both aluminum and cast iron engine blocks. The center layer is stainless steel and can be varied in thickness to achieve specific compression ratios; this one has a compressed thickness of 0.120 inches and an 84mm bore, making it suitable for specific engine builds.

Cometic MLS gaskets are designed to provide maximum sealing performance without the need for additional sealants, simplifying installation. They are well-suited for engines that see higher output than stock, offering a durable sealing solution.
