Product Information
Krytox™ Lubricants
Krytox oils and greases are based on perfluoropolyether(PFPE) oils. Krytox™ synthetic fluorinated lubricants
are used in extreme conditions, such as continuous
high temperatures up to 288 °C (550 °F) and higher
temperatures for shorter periods, depending on productgrade limits. Chemically inert and safe for use aroundhazardous chemicals, these lubricants are nonflammableand safe for use in oxygen service. Krytox™ oils andgreases do not damage plastics or elastomers, norcause corrosion to metals. They are commonly used
as lubricants in aerospace, automotive, industrial, andsemiconductor applications, as well as solving many otherroutine lubrication problems.

Krytox™ AGL 829 Grease
Krytox AGL 829 grease contains extreme pressure andanti-corrosion additives. Typical applications include thosein potentially corrosive atmospheres, where vibrationalor shock loading may be significant and an element will
spend more time experiencing mixed film or boundary
lubrication versus the desired full film or hydrodynamic
lubrication. Krytox™ AGL 829 grease is specificallydesigned to lubricate gears and their associated bearings
under relatively low temperature conditions.

Typical Applications
Applications for Krytox lubricants are generally ofa critical nature. These lubricants are expected tobe durable in the most aggressive environments.
Temperatures in all industries are reaching extremes
for conventional lubricants, and lubricants are now
often considered an integral part of the design. Wherefailure of components is not an option, whether becauseof durability, warranty, safety, loss of productivity, ordowntime, Krytox™ is the lubricant of choice in a wide
range of industries and applications.
™

Krytox™ oils and greases are silicone-free. They do notcontain any VOC* materials or chlorine, are not hazardous
to the atmosphere or ozone layer, and are biologically andenvironmentally inert.

New, unlubricated components and bearings are typicallycoated with rust preventive oils to prevent damage while
they are in storage before use. New components should
be inspected for damage and cleanliness before use.
The greases or preservative oils used in storage need tobe removed before using Krytox™ as a lubricant. Bearing
life tests on uncleaned bearings have shown reduced
life in high-temperature, high-speed tests where thebearing was filled with a minimum amount of grease. The
preservatives coat the metal surface to prevent rusting;so, they can also prevent the grease from adhering,causing them to be thrown off by the action of thebearing. The preservatives will also oxidize and harden andcan create debris that will contaminate the grease.
Storage and Shelf Life*

Volatile organic compounds

Krytox™ grease and oil lubricants have an indefinite
shelf life if unopened and stored in a clean, dry, and coollocation.
