Product Information
Krytox™ oils and greases are based on perfluoropolyether(PFPE) oils. This series of synthetic fluorinated lubricants
are used in extreme conditions, such as continuous hightemperatures up to 260 °C (500 °F), and will surviveshort-term peak temperatures of up to 270 °C (518 °F).
Chemically inert and safe for use around most chemicals,
these lubricants are nonflammable and are also safe for usein oxygen service. Krytox™ oils and greases do not damage
plastics or elastomers, nor cause corrosion to metals. They
are commonly used as lubricants in aerospace, automotive,industrial, and semiconductor applications, as well as insolving many other routine lubrication problems. In addition,
they provide exceptionally long lifetimes in sealed-for-life
bearings and extend re-lubrication intervals in bearings that
require re-lubrication.

Krytox™ GPL 106 Oil
Krytox™ GPL 106 oil is a clear, colorless, fluorinated synthetic
oil that is non-reactive, nonflammable, safe in chemical andoxygen service, and is long lasting. Krytox™ is a PFPE—also
called perfluoroalkylether (PFAE) or perfluoropolyalkylether(PFPAE)—with the following chemical structure:
F- (CF-CF2-O)n-CF2CF3|			CF3			

where n = 10–60

The polymer chain is completely saturated and contains
only carbon, oxygen, and fluorine. On a weight basis, a typical
Krytox™ oil contains 21.6% carbon, 9.4% oxygen, and69.0% fluorine.

Krytox™ GPL 206 Grease
Krytox™ GPL 206 grease is PTFE thickened, contains noadditives, and can be used on components that come incontact with chemicals. Typical applications include valves,instruments, or bearings in contact with chemicals, including
alcohols, ammonia, solvents, steam, acids and bases, andoxygen systems, such as LOX and GOX. They are commonlyused as seal and O-ring lubricants, and are compatible with all
types of seals.

Krytox™ GPL 216 Grease
Krytox™ GPL 216 grease contains molybdenum disulfide forextreme pressure (EP) conditions and should be used forslow speed or heavily loaded applications, where there is nodanger of the molybdenum disulfide additive reacting withchemicals or causing contamination.

Krytox™ GPL 226 Grease
Krytox™ GPL 226 grease contains an anti-corrosion/antiwear inhibitor and is ideal for corrosive environments, where
there is no danger of the sodium nitrite additive reactingwith chemicals or causing contamination problems. Typicalapplications are automotive bearings, sealed pump bearings,
electric motor bearings, and general-purpose bearings.
Krytox™ oils and greases are silicone free. They do not containany VOC materials or chlorine, and are not hazardous tothe atmosphere or ozone layer. They are biologically andenvironmentally inert.
The fully fluorinated Krytox™ high-temperature stability
provides bottom-line savings from improved reliability, and areduction in grease usage and manpower through extended
re-lubrication intervals. Excellent film strength reduces wear
to reduce maintenance costs. Under high loads, the viscosity
increases to provide support and absorb the pressure.

Preparing the Application for Krytox™
New components often have organic rust preventive oils
or greases on them to prevent damage while they are instorage before use. New bearings should be inspected fordamage and cleanliness before use. The components must
be completely cleaned of greases or preservative oils whenusing Krytox™ as a lubricant. Failure to do so could result
in reduced bearing life. Bearing life tests on un-cleaned
bearings have shown reduced life in high temperature, highspeed tests, where the bearing was filled with a minimumKrytox™

Performance Lubricantsamount of grease. The preservatives coat the metal surface
to prevent rusting; so, they can also prevent the grease fromadhering, causing them to be thrown off by the action of thebearing. They could also oxidize and harden, and can create
debris that will contaminate the grease.

Storage and Shelf Life

These greases are compatible with other PFPE/PTFEgreases, but PFPE lubricants should not be mixed with othercommon types of lubricants.

Because of the inert, non-oxidizing nature of the ingredients,
Krytox™ grease and oil lubricants have an indefinite shelf life,
if unopened and stored in a clean, dry location. Greases mightshow oil separation after extended storage, but mixing thefree oil back into the grease will return the grease to normal
useable condition.
