Overview
Krytox™ 240AD is a white, buttery grease with all the same properties as the 143 series oils it is made from but in grease form. Krytox™ 240AD is formulated from a clear, colorless, fluorinated perfluoropolyether (PFPE) synthetic base oil that is nonreactive, nonflammable, and safe in chemical and oxygen service. It exhibits exceptionally long-lasting operational life.
