Krytox GPL 207/206 PFPE / PTFE grease
inert, oxygen compatible greases

64-001060	Krytox GPL 207 PFPE / PTFE grease, 60g tube


Krytox GPL 207 and GPL206  are a long-lasting, white buttery greases which are nonreactive, nonflammable, safe in chemical and oxygen service. It only contains carbon, oxygen and fluorine, but no hydrogen or silicone. It will not burn or support combustion. It is an ideal grease for vacuum parts which are exposed to air such as rods in vacuum loading locks, vacuum door seals, moving aperture holders and valves. Krytox does not degrade in contact with air, does not contain any silicone and is basically chemically inert.  Krytox GPL 207/206 greases consist of Krytox perfluoropolyether (PFPE) fluorinated synthetic oil and Krytox 2000 polytetrafluoroethylene (PTFE). It also exhibits excellent anti-seize properties. It can be used up to a service temperature of 288°C. Originally a Dupont product, now a product of Chemours. Krytox GPL 207/206 are alternatives for Braycote 803 and the OC Five / OC Seven greases. 
Due to initial outgassing, it is recommended to pre-condition the grease under vacuum and operating temperature until the required vacuum level has been reached.

Typical applications include:

  • seal and lubricate in oxygen applications
  • seal and lubricate vacuum components
  • seal and lubricate load-lock rods
  • seal and lubricate vacuum feedthroughs
  • lubricate O-rings on vacuum systems
  • lubricate seals in aggressive chemical environments
