Cometic Armor Clad exhaust gaskets use an Armor-400 high-temperature, high performance fiber core. The core is laminated on both sides with an ETP steel cover and mechanically bonded without the use of adhesives. This innovative process allows the material to withstand temperatures of up to 2,000 degrees and is compressible to seal those less-than-perfect surfaces.
