Krytox FPG 028 - Exceptional Chemical and Oxygen Resistance Grease


Krytox FPG 028 is a smooth, buttery, perfluoropolyether (PFPE)-based white grease thickened with a special, high-performance polytetrafluoroethylene (PTFE) thickener. It was developed to operate over a wide temperature range (–73 to 204 °C; –99 to 399 °F)) and to be resistant to hydrocarbon fuel, liquid oxygen and a variety of other chemicals. Krytox™ FPG 028 operates well under severe conditions and can be used for bearings and gears, and as a lubricant for O-rings and elastomers. The Department of Defense’s Defense Logistics Agency (DLA) has assigned Commercial and Government Entity (CAGE) Code 7GFT8 to The Chemours Company.
