The Krytox NRT 8900 series oils and greases deliver nonreactive, nonflammable, long-lasting performance, even under the demanding temperatures and pressures of reactive gas service. Krytox NRT lubricants are compatible with oxygen and other reactive chemicals, and are extremely resistant to water washout. Krytox NRT 8900 lubricants are also compatible with polymers used in seals, O-rings, and valves.

The superior film-forming capability of Krytox lubricants provide a thick oil layer that reduces friction and wear, extending equipment life in severe duty applications. The non-oxidizing nature of the oils makes the greases last longer. The oils don’t gum up as they age; so, they won’t harden the greases and cause catastrophic failure. Krytox oils and greases are perfluoropolyether (PFPE) lubricants—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE). Many of the NRT series of Krytox™ greases are thickened with a unique polytetrafluoroethylene (PTFE) with the formula (CF2-CF2)n. This special high efficiency thickener has a melting point of 325 °C (617 °F), low molecular weight, and submicron (0.2 μm) particle size.
