Cometic Peugeot P405 M-16 85mm .027 inch MLS Head Gasket

This Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. When compressed, it measures 0.027 inches thick, making it a solid choice for sealing the combustion chamber in your Peugeot 405. MLS gaskets are well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as they can handle the different expansion rates between these materials without issue.

The stainless steel construction offers increased strength and resilience, helping the gasket rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant synthetic rubber designed to perform in demanding sealing environments, even on various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness control. This design means the gasket requires no additional sealants for installation, simplifying the process.
