Cometic Mazda FS-DE/FS-DET .036in MLS Cylinder Head Gasket - 84mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with an 84mm bore and a compressed thickness of 0.036 inches, making it a solid choice for your Mazda FS-DE or FS-DET engine. MLS gaskets are known for their ability to handle high output engines because they are constructed from multiple layers of stainless steel, which also helps them resist corrosion and maintain their shape under stress. This design means you don't need to add any extra sealants when you install it.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it ideal for sealing between aluminum heads and either aluminum or cast iron blocks, as it can manage the different expansion rates and shearing forces that occur. The center layer is stainless steel, and Cometic uses different thicknesses for this layer to meet various sealing requirements.
