FKM fluororubber Key benefits aging, heat and oil resistance to extend the life of seals, gaskets and other oilcontact components in demanding environments. Broad compatibility with almost all lubricating oils, fuels and gasoline, reducing the need for multiple elastomer types in a system. Resists hardening when exposed to oils containing extreme pressure EP additives, helping maintain seal integrity in EP environments. Wide operating temperature range supports use in hot machines and engines. Material and performance Material: FKM fluororubber Temperature range: 20 to 220 C Compatibility: suitable for almost all lubricating oils, fuels and gasoline EP additive compatibility: not easy to harden in oils containing EP additives Important considerations Cold resistance: limited temperature wear resistance: limited Permanent compression deformation: large ( compression set under longterm static load) Applications and use scenarios Automotive fuel system seals and gaskets (eg, pump and injector seals) exposed to gasoline and lubricating oils, where broad oil compatibility and heat resistance are required. Industrial machinery seals in hydraulic systems using mineral or synthetic oils, where thermal stability and oil compatibility are important. Sealing parts in engines or gearboxes that operate with oils containing extreme pressure additives, where EP additive resistance to hardening is advantageous. Notes Suitable for static or lowcycling sealing applications due to its relatively compression set. Designed to perform within the specified temperature range and fluid compatibility without additional modifications.
