Krytox™ GPL 226 Grease

Synthetic fluorinated grease based on perfluoropolyether (PFPE oil) for extreme operating conditions and temperatures up to 260 °C

Krytox™ GPL 226 is a high-temperature anti-corrosion grease that provides protection against rust, high corrosion, temperature protection and anti-wear,

Will not spontaneously ignite in oxygen at temperatures up to 482 ºC (900 ºF) or pressures up to 350 bar.
Safe, non-reactive and non-flammable when used with reactive chemicals
and safe for use in all areas of oxygen service.

Typical applications

  • bearings (paper industry, textile equipment, paint shops, fans, production of aluminum cans, high-speed motors)
  • chemical industry: machines in contact with acids, bases, solvents and reactive gases.
  • chemical processing valves,
  • fans, pumps, motors, centrifuges,
  • energy generation: bearings (not washed out by water, steam or solvents)
  • oxygen systems, including LOX and GOX.
  • seals and o-rings - compatible with all types of seals

Features and benefits

  • 100% compatible with oxygen
  • Excellent lubricity leading to longer equipment life
  • Completely non-combustible, which can eliminate the need for ancillary systems designed to prevent fires and explosions
  • Safe when used with other oxidizing chemicals such as fluorine, chlorine and bromine
  • Maintaining lubrication at extremely high temperatures up to + 260 °C
  • Compatible with all materials elastomers, plastics, metals
  • NSF H1 food grade certified for incidental food contact

Storage and durability

Due to the inert, non-oxidizing nature of the ingredients, Krytox™ greases and oils have an indefinite shelf life if left unopened and stored in a clean, dry place.

    Application in the chemical industry and oxygen services

    Field tested Krytox™ high performance lubricants have been independently researched and tested by companies and organizations such as Air Liquide, BAM, NASA and General Dynamics and have been proven to be compatible with oxygen and other reactive chemicals.

    Conventional mineral oils and synthetic lubricants are not compatible with reactive gases such as oxygen or other oxidizing chemicals.
    In contrast, Krytox™ oils and greases are non-flammable, chemically inert, thermally stable and safe for use in all areas of oxygen service.
