Krytox™ 240AB Aerospace Grease. Low to medium molecular weight base oil without additives. Meets MIL-PRF-27617 Type II.
Krytox™ 240AB is a white buttery grease with all of the same properties as the 143 series oils that they are made from, but they are in grease form. The properties that they are clear, colorless, fluorinated synthetic oils that are nonreactive, nonflammable, safe in chemical and oxygen service, and are long-lasting. Meets MIL-PRF-27617 Type II and NSN 9150-01-088-0498.
Lighter to medium of the premium AAND greases for use in applications that do not require additional corrosion inhibitors or extreme pressure additives.
Krytox™ 240AB is a lighter of the common aerospace grades, engineered for precise performance characteristics in demanding aerospace applications.

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.
