AGL 683

Performance Lubricants

Grease for Aviation Gearbox Applications

Product Information
Krytox™ AGL 683 is a yellow, creamy grease basedon perfluoropolyether (PFPE) oil and thickened with
polytetrafluoroethylene (PTFE).This product is specificallydesigned to lubricate gears and their associated bearings
under relatively low temperature conditions.
All Krytox™ oils and greases are synthetic fluorinatedlubricants, designed for use in critical applications andthe most aggressive environments. They perform underextreme, continuous high temperatures up to 280 °C(536 °F) and in even higher temperatures for shorter
periods, depending on product grade limits. They are
nonflammable, chemically inert, and safe for use withreactive gas service and hazardous chemicals. They do
not damage plastics or elastomers, nor cause corrosion
to metals. Krytox™ oils and greases are silicone-free. They
do not contain any VOC materials or chlorine. Krytox™
lubricants are commonly used in aerospace, automotive,industrial, and semiconductor applications, as well as
many routine lubrication applications.
Krytox™ AGL 683 grease contains extreme pressure
and anti-corrosion additives for applications in corrosive
atmospheres or with significant shock loading, where
an element experiences greater mixed film or boundary
lubrication than full film or hydrodynamic lubrication.
Krytox™ AGL 683 grease will also provide superior
performance in applications prone to significant fretting
corrosion.

Cleaning and Packing the Bearing

Storage and Shelf Life

Inspect new components for damage and cleanlinessbefore use. New non-lubricated components and bearings
are typically coated with rust preventive oils to prevent
damage while they are in storage. The oils must beremoved when using Krytox™. Failure to do so could result
in reduced component life. Bearing life tests on uncleaned
bearings filled with a small amount of grease have shown
reduced life in high temperature, high speed tests. The
preservatives can prevent the grease from adhering to
the bearing and can oxidize and harden, contaminating thegrease with debris.

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