Krytox™ NRT 8908 Grease | For Reactive Gas Service
Superior film-forming capability that reduces wear
Krytox NRT 8908 grease delivers 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 lubricants are also compatible with polymers used in seals, O-rings, and valves. Providing excellent lubrication options for valves, regulators, seals, and pump and motor bearings at a wide range of operating conditions. Krytox NRT 8908 grease has been formulated for use in cold to ambient conditions, and is recommended as a cost-effective valve packing and seal lubricant for O-rings.
All NRT oils and greases have been tested by West German Federal Institute for Materials Testing (BAM). Krytox lubricants have been independently tested by organizations, including BOC, Air Liquide, NASA, General Dynamics, and Praxair, and proven acceptable for oxygen and other reactive chemical compatibility. For additional Krytox lubrication series info, please see Krytox VPF/LVP or Krytox GPL 22X series.
Why Krytox NRT 8908?
Krytox™ products are fully synthetic, not petroleum- based and totally inert, so Krytox™ oils and greases do not react with anything in the environment. Unlike other lubricants, at temperatures under 350 ºC (662 °F), Krytox™ oil does not oxidize or break down into other substances that could be harmful.
