Cometic Peugeot P405 M-16 84mm .040 inch MLS Head Gasket

If you're rebuilding the top end of your 1989-1991 Peugeot 405, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically made for the XU9J4/Z and XU10J2/4 engines, ensuring a proper seal between the cylinder head and the engine block. This gasket is designed to handle the demands of modern engines, providing maximum sealing performance without needing any additional sealants.

Cometic builds these MLS gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This Viton coating is crucial for meeting the challenges of various sealing environments and surface finishes. The center layer is uncoated stainless steel, and its thickness can be adjusted to meet different requirements, with this specific gasket having a compressed operating thickness of 0.040 inches and an 84mm bore.
