Krytox GPL Oils 100–107 oils are clear, colorless, fluorinated synthetic oils that are nonreactive, nonflammable, safe in chemical and oxygen service, and are long-lasting. Krytox is a perfluoropolyether (PFPE)—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE).

Krytox GPL 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 in solving many other routine lubrication problems.

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.

These oils are compatible with other PFPE/PTFE greases but PFPE lubricants should not be mixed with other common 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 might show oil separation after extended storage but mixing the free oil back into the grease will return the grease to normal usable condition.
