DuPont Lubricants for Aerospace

Krytox® was first developed by DuPont in the 1960s to meet the special lubrication needs 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:

  • 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 Applications (aerospace conditions and environments)

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

Aerospace Specific 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
