Krytox 250AC Grease | High-Performance Aerospace & Aviation Grease
Molybdenum disulfide additive, For highly loaded gears and bearings
Krytox™ Aerospace Lubricants was initially developed by DuPont in the early 1960s specifically for the precise and demanding lubrication needs of the aerospace industry. Krytox synthetic lubricants have since replaced hundreds of special-formula, hydrocarbon-based oils and greases throughout the aerospace and aviation industries, thanks to a long list of superior performance characteristics and certifications. Since the first commercial application over 50 years ago, Krytox synthetic lubricants have delivered consistent, superior, reliable, and extended performance. Today, with new additives for new challenges, Krytox lubricants continue to deliver extreme performance under the most extreme conditions. Krytox 250AC is the lubricant of choice for demanding conditions —high and low temperatures, extreme pressure, and harsh environments.
Why Krytox 250AC?
Krytox greases are used in a variety of limited-motion mount systems associated with aircraft engines, such as an oil tank mount bracket for a Trent 1000 engine. Krytox lubricants can be used to improve the performance of traditionally non-lubricated materials, such as DuPont™ Vespel® CR-6100 bushings. For Krytox Aviation Oils, please see Krytox™ 143 series.
