KRYTOX™ NRT 8904 Non-Flammable Performance Grease

The NRT series of Krytox™ 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 lubricants are also compatible with polymers used in seals, O-rings, and valves.

KRYTOX™ NRT 8904 Non-Flammable Performance Grease

Krytox™ NRT 8904 lubricant provides a thick oil layer that reduces friction and wear; extending equipment life and reducing need for repair in severe duty applications. The diverse and versatile nature of the oils makes the greases last longer, allowing users to lower costs and optimize their repair and maintenance processes.

Krytox™ NRT series is tailored to applications in the most demanding and harsh environments. The NRT range is ‘non-reactive’, which allows use in environments with oxygen, flammable materials and other reactive chemicals.
