Product Information
Krytox™ oils and greases are based on perfluoropolyether(PFPE) oils. These synthetic fluorinated lubricants are usedin extreme conditions, such as continuous high temperatures
up to 288 °C (550 °F), and higher temperatures for shorter
periods, depending on product grade limits. Chemically inertand safe for use around hazardous chemicals and reactivegases, these lubricants are nonflammable and safe for use
in oxygen service. Krytox™ oils and greases do not damage
plastics or elastomers, nor cause corrosion to metals. Krytox™
lubricants provide an exceptionally long lifetime in sealed-forlife bearings and extend re-lubrication intervals in bearings
that do require re-lubrication. Typical applications include
automotive, sealed pump, electric motor, and general-purpose
bearings.
Krytox™ PFPE has the following chemical structure:
F-(CF-CF2-O)n-CF2CF3|			CF3where n=10–60

Krytox Oil Grade GPL 107™

Krytox™ oil grade GPL 107 is a clear, colorless fluorinatedsynthetic oil that is non-reactive, nonflammable, safe inchemical and oxygen service, and long lasting.

Krytox™ Grease Grade GPL 2071
Krytox™ grease grade GPL 207 is thickened with polytetrafluoroethylene (PTFE), contains no additives, and can beused on components that come into contact with chemicals.
Typical applications include valves, instruments, or bearings
that contact chemicals, including alcohols, ammonia, solvents,steam, acids, bases, and oxygen systems, including LOX andGOX. Krytox™ GPL 207 is commonly used as a seal and O-ring
lubricant, compatible with seals typically used in industry, andalso NSF H-1 food grade registered.

Krytox™ Grease Grade GPL 2272
Krytox™ grease grade GPL 227 contains an anti-corrosion/
anti-wear inhibitor and is ideal for corrosive environments
where there is no danger of the sodium nitrite additive
reacting with chemicals or causing contamination problems.
Krytox™ GPL 227 is also NSF H-1 food grade registered.

Krytox™ lubricants have been used in the power generation industry sincethe 1980s in both common and extreme applications, from turbine auxiliary
systems to power plant maintenance, repair, and operations (MRO).

Krytox™ Oil Grade XP 1A7
Krytox™ oil grade XP 1A7 is formulated using a patented
soluble additive for superior anti-wear/extreme pressure
performance and corrosion protection.
Krytox™ oils and greases are silicone-free. They do not containany volatile organic compound materials or chlorine and are
not hazardous to the atmosphere or ozone layer. They are
biologically and environmentally inert.
The fully fluorinated Krytox™ lubricant high-temperaturestability provides bottom-line savings from improved reliability
and a reduction in grease usage and manpower throughextended re-lubrication intervals. Excellent film strength
reduces wear to lower maintenance costs. Under high loads,
the viscosity increases to provide support and absorb pressure.

Preparing the Application for Krytox™ Lubricant
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 when
preparing to use Krytox™ lubricant. Failure to do so could

Krytox™ GPL 207 is NSF152950 registered.

result in reduced bearing life. Bearing life tests on uncleaned
bearings have shown reduced life in high temperature, highspeed tests, where the bearing was filled with a minimum
amount 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, creating debris
that will contaminate the grease.

Packaging

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

Krytox™ greases are available in 2 oz and 8 oz tubes, 0.5 kg
and larger containers, and 0.8 kg/1.75 lb cartridges. Oils areavailable in 0.5 kg and larger bottles as well as pails.

Storage and Shelf LifeThe XP series of Krytox™ lubricants can develop an odor andslight amber/pinkish color over time. The XP series has athree-year shelf life and recommended maximum operating
temperature of 182 °C (360 °F). Testing has shown that theseproducts retain their anti-rust and anti-wear properties andperform well past the end of the recommended three-year
shelf life. Keep product sealed, and store in a cool, dry place.
