Performance Lubricants

Extreme performance lubricants for bearings, valves, seals andother applications under extreme conditions

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 204 °C (400 °F), and will surviveshort-term peak temperatures of up to 220 °C (429°F). Chemically inert and safe for use around hazardous
chemicals, these lubricants are nonflammable and also
safe for use in oxygen service. Krytox™ oils and greases do
not damage plastics or elastomers, nor cause corrosion tometals. They are commonly used as lubricants in aerospace,automotive, industrial, and semiconductor applications, aswell as in solving many other routine lubrication problems.
In addition, they provide exceptionally long lifetimes insealed-for-life bearings and extend re-lubrication intervals inbearings that require re-lubrication.

Krytox™ GPL 105 Oil
Krytox™ GPL 105 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, and 69.0%
fluorine.

Krytox™ GPL 205 Grease
Krytox™ GPL 205 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, including LOX and GOX. They are commonlyused as seal and O-ring lubricants, and are compatible with all
types of seals.

Krytox™ GPL 215 Grease
Krytox™ GPL 215 grease contains molybdenum disulfide forextreme pressure (EP) conditions and should be used for slow
speed or heavily loaded applications, where there is no dangerof the molybdenum disulfide additive reacting with chemicals orcausing contamination.

Krytox™ GPL 225 Grease
Krytox™ GPL 225 grease contains an anti-corrosion/anti-wear
inhibitor and is ideal for corrosive environments, where there isno danger of the sodium nitrite additive reacting with chemicals
or causing contamination problems. Typical applications areautomotive bearings, sealed pump bearings, electric motorbearings, 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 a reduction ingrease usage and manpower through extended re-lubricationintervals. Excellent film strength reduces wear to reduce
maintenance costs. Under high loads, the viscosity increases toprovide support and absorb the pressure.

Preparing the Application for Krytox™
New components often have organic rust preventive oils orgreases on them to prevent damage while they are in storage
before use. New bearings should be inspected for damage andcleanliness before use. The components must be completely
cleaned of greases or preservative oils when using Krytox™ asa lubricant. Failure to do so could result in reduced bearing life.
Bearing life tests on uncleaned bearings have shown reduced
life in high temperature, high speed tests, where the bearing wasfilled with a minimum amount of grease. The preservatives coatKrytox™

the metal surface to prevent rusting; so, they can also preventthe grease from adhering, causing them to be thrown off by
the action of the bearing. They also will 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.
