Krytox™ 143AA Oil

Krytox 143AA Oil | Designed for the Aerospace Industry

Superior Long Lasting Lubrication

Krytox 143AA oil is a clear, colorless, fluorinated synthetic oil that is non-reactive, 100% nonflammable, safe in chemical and oxygen service, and are long-lasting. Krytox is a perfluoropolyether (PFPE)—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE). The polymer chain is completely saturated and contains only carbon, oxygen, and fluorine. On a weight basis, a typical Krytox™ oil contains 21.6% carbon, 9.4% oxygen, and 69.0% fluorine. All standard grades of grease are thickened with high efficiency PTFE, whose formula is (CF2-CF2)n. This special high efficiency thickener has a melting point of 325 °C (617 °F), and has low molecular weight and submicron (0.2 µ) particle size for higher performance in bearings.

Why Krytox 143AA Oil?

Krytox™ 240 series greases are white buttery greases with all of the same properties as our 143 series oils that they are made from, but they are in grease form. Krytox™ 250 series EP greases are black greases that contain molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings. These grades provide rust protection at ambient temperatures, corrosion protection at high temperatures, and antiwear protection. Krytox™ 240 AC, 240 AB, and 240 AZ Grade 1 greases now have NSF approval for incidental food contact (H-1) in and around food processing areas. These three products meet the requirements of Mil Spec PRF 27617, Types 1, 2, and 3.
