Aerospace, Aviation & Defense Applications

Krytox® aerospace lubricants have demonstrated the broad applicability to replace hundreds of purpose-formulated conventional oils and greases throughout the aerospace and aviation industries through the state-of-the-art fluoropolymer technology of DuPont.

Krytox® aerospace lubricant was first developed by DuPont in the 1960s to meet the exacting lubrication specifications of the aerospace industry.

• Suborbital, Orbital, and Deep Space Flight -- Reliability and long service life of mission-critical mechanical components in the face of high vacuum, temperature extremes, contact with fuels and oxidizers, and radiation exposure
• Commercial, Corporate, and Military Aviation -- Reduced maintenance requirements, improved safety and reliability, compliance with a wide range of military specifications

Based on DuPont-patented fluoropolymer technology, Krytox® performance lubricants have demonstrated the broad applicability to replace hundreds of purpose-formulated conventional oils and greases throughout the aerospace industry with properties such as:

• DuPont™ Krytox® 240AB and 240AC grease grades are NSF H1 certified for incidental food contact for use in and around food processing areas
• Wide temperature ranges: -70 to 399°C (-100 to 750°F)
• Robust resistance to change in properties over time, in the face of harsh environmental conditions such as shock, vibration, heat and pressure; aggressive chemical environments, including rocket fuels and oxidizers; and intense radiation exposure
• Resistance to vaporization losses in the vacuum of high-altitude flight, orbit, and deep space
• Excellent frictional properties for long wear and low energy consumption
• Compatibility with all metals, elastomers, plastics, paints and finishes
• World-class technical service

General Aerospace Lubricant Applications

• Bearings -- all types
• Seals -- valves and pumps
• O-rings -- sealants, lubricants

Advanced Applications

• Oxgen systems -- valve and pump packing seals, mechanical seals and connectors
• Rocket engines, liquid fueled -- turbines, gimbals, pumps, gears, valves with fuel/oxidizer exposure

Literature on Krytox® Aerospace Lubricants

• DuPont™ Krytox® 240 AZ, AB, and AC greases meet Mil-PRF-27617 Type I, II, and III specifications.
• Typical Properties of Krytox® Aerospace Grade Oils and Greases
• Solvents for Krytox®
