Durlon® FGM316 is reinforced with a 0.004″ thick 316 stainless steel foil insert, enhancing mechanical strength while maintaining excellent conformability. Designed for high-temperature and high-pressure service, this material delivers reliable sealing in steam, hydrocarbons, and aggressive chemical environments. Its balanced construction resists gasket creep and blowout, making it a preferred choice for flanges, pumps, valves, and heat exchangers.
