Aerospace Grades


Krytox™ Aerospace Grade Oils and Greases

Applications for Krytox™ performance lubricants are generally of a critical nature with temperatures in all industries reaching extremes for conventional lubricants. They are expected to be durable in the most aggressive environments and are now often considered an integral part of the design. Where failure of components is not an option, whether because of durability, warranty, safety, loss of productivity or down time, is the lubricant of choice in a wide range of industries and applications.

In the aerospace industry, Krytox™ oils and greases are applied on various settings spanning from bearings and sealants to o-rings and oxygen systems, and are valuable assets to the aerospace industry due to their superior performance in a wide range of temperatures scaling from –100 to 750 ºF (70 to 399ºC). In addition, it is robust in harsh environments and has excellent frictional properties, allowing it to resist change in properties over time, provide longer wear, and lower energy consumption. Lubricants are compatible with all metals, elastomers, plastics, paints and finishes. Due to the intense and severe circumstance of the aerospace industry, it can be expected that Krytox™ performance lubricants deliver a high level of product excellence.

Based on the fluoropolymer technology of , 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:

• Low outgassing

• Wide temperature range

• 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

Aerospace-Specific Applications

  • Oxygen systems - valve and pump packing seals, mechanical seals and connectors.

  • Rocket engines, liquid fueled - turbines, gimbals, pumps, gears, valves with fuel/oxidizer exposure.

  • Actuators - mechanical/gear-type actuators for control valves and systems

  •  Mechanical components - spline shafts, control linkages.

  • 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™ 143 series oils are clear, colorless, fluorinated synthetic oils that are non-reactive, nonflammable, safe in chemical and oxygen service, and are long lasting.

All standard grades of grease are thickened with polytetrafluroethylene (PTFE). This special high efficiency thickener has a melting point of 617ºF (325ºC) and has low molecular weight and sun-micron (0.2M) particle size for higher performance in bearings.

240 series greases are white buttery greases with all of the same properties as the GPL 100-107 oils that are made from, but they are in grease form.

283 series anticorrosion greases are white greases that contain sodium nitrite. These grades provide rust protection at ambient temperatures, corrosion protection at high temperatures and anti-wear protection.

250 series greases are black in color that contains molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings.
