Cometic Peugeot XU9J4/XU9J4Z/XU10J2/XU10J4 .066in MLS Cylinder Head Gasket - 85mm Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on your 1989-1991 Peugeot 405, this gasket is designed to provide a strong seal for your engine's cylinder head. It's built with multiple layers of stainless steel, which gives it increased strength and helps it resist corrosion. This construction also allows the gasket to rebound and maintain its seal even under stress.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This makes it suitable for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can handle the different expansion rates between these metals. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, with this particular gasket having a compressed operating thickness of 0.066 inches and an 85mm bore. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
