Durlon 9400 is a specialty PTFE gasket specifically designed for hydrofluoric acid, anhydrous hydrogen fluoride, and other highly aggressive fluorinated media. Its unique filler formulation offers superior chemical resistance where standard PTFE materials would degrade or swell. Frequently used in railcar flanges, chemical reactors, and fluorine-based process lines, it provides safe, long-lasting sealing in extremely corrosive environments.
