Often used to clean lubricants off compressed gas equipment and fittings, these solvent-based degreasers have a contaminant concentration below 1 ppm to ensure no residue or particles are left behind that can hinder the operation of valves, sensors, and controls. They contain Vertrel™ to remove long-lasting lubricants, such as DuPont/Chemours Krytox. They are nonflammable and less hazardous than other solvents that remove lubricants, such as nPB, PERC, and TCE. Use these degreasers as the primary cleaner or as a final rinse to ensure parts are completely clean. They evaporate quickly, allowing parts to be used shortly after cleaning.
