Krytox GPL 206 are greases are based on perfluoropolyether (PFPE) oils. This series of synthetic fluorinated lubricants are used in extreme conditions such as continuous high temperatures up to 260°C (500°F) and will survive short 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 use in oxygen service.

Krytox GPL 206 grease does 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 in solving many other routine lubrication problems. In addition, they provide exceptionally long lifetimes in sealed-for-life bearings and extend relubrication intervals in bearings that require relubrication.

The Krytox GPL 206 grease is PTFE thickened, contains no additives and can be used on components that come in contact with chemicals. Typical applications include valves, instruments or bearings in contact with chemicals including alcohols, ammonia, solvents, steam, acids and bases, and oxygen systems including LOX and GOX. They are commonly used as seal and o-ring lubricants and are compatible with all types of seals.

New components often have organic rust preventive oils or greases on them to prevent damage while they are in storage before use. New bearings should be inspected for damage and cleanliness before use. The components must be completely cleaned of greases or preservative oils when using 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, high speed 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 from adhering, causing them to be thrown off by the action of the bearing. They could also oxidize and harden and can create debris which will contaminate the grease.
