Krytox 143AD Oil | Designed for the Aerospace Industry
Superior Long Lasting Lubrication
Krytox 143AD 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 143AD 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. Krytox™ 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 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.
