Safety and Longevity in Reactive Gas Environments
Krytox™ NRT (nonreactive) greases deliver inert, nonflammable, long-lasting performance—even when dealing with reactive gases. They are compatible with oxygen and other reactive chemicals and are extremely resistant to water washout.
Additionally, Krytox™ NRT greases are compatible with polymers used in seals, O-rings, and valves. The superior film-forming capability of Krytox™ performance lubricants provide a thick oil layer that reduces friction and wear, extending equipment life.
Features and Benefits of Krytox™ NRT Greases
Krytox™ NRT greases are widely used in applications with exposure to reactive gases, such as chemical processing.
Key properties and benefits of Krytox™ NRT greases include:
- Extended equipment life
- No auto-ignition at temperatures up to 482 °C (900 °F) in oxygen
- No ignition at pressures up to 350 bar
Different Grades for Different Applications
Krytox™ NRT greases come in several grades, each with its own unique properties for special uses.
Krytox™ NRT 8900 grease is formulated for use in cold-to-ambient conditions and recommended as cost-effective valve packing and seal lubricant for O-rings.
Krytox™ NRT 8904 and 8906 lubricants provide excellent options for valves, regulators, and seals, as well as pump and motor bearings for various operating conditions.
Krytox™ NRT 8908 grease is a special high-pressure oxygen paste with excellent lubrication over a broad temperature range. Formulated with special oils and thickeners for use in the high-pressure oxygen industry, NRT 8908 received a 340 bar rating at 60 °C (140 °F) in the BAM oxygen reactivity test.
