Krytox™ FPG 028 - Flight Program Grease - Formulated for the most demanding aerospace applications. Lower Molecular Weight.
Krytox™ FPG 028 is a smooth, buttery, white grease. It has been developed to operate over a wide temperature range -73°C to 204°C (-99°F to 399°F), to be resistant to hydrocarbon fuel and liquid oxygen, and to be used as a lubricant in aircraft, aerospace vehicles, and supporting equipment. Krytox™ FPG 028 is certified and meets all the requirements of MIL-PRF-27617 Type IV.
It is designed to operate under severe conditions, and can be used for bearings, gears, and as a lubricant for O-rings and elastomers.
Meets MIL-PRF-27617 Type IV specification.

Krytox™ greases are nontoxic lubricants that maintain their lubricity and viscosity properties to reduce maintenance costs associated with re-lubrication, component failure, and downtime in demanding applications. They are created by thickening synthetic perfluoropolyether-based oil (PFPE) with polytetrafluoroethylene (PTFE) powder. The PTFE thickener forms a barrier that holds the base oil at friction contact points for long-term lubrication, without requiring complicated oil recirculation systems. Anit-corrosion, High Temperature and High Pressure additives are also provided for specialized applications.
