Description
Castrol Brayco® 1720 Plus series oils are clear, colorless low molecular weight perfluoroether oils with added
corrosion preventative. The oils are chemically inert to virtually all chemicals, and safe to use in direct contact
with oxidants such as LOX/ GOX and chlorine. Castrol Brayco® 1720 Plus series oils are nonflammable and nontoxic. Castrol Fluoroclean™ X100 and Castrol Fluoroclean™ HE can be used to clean this product. Refer to the
data sheets for Castrol Fluoroclean™ X100 and Castrol Fluoroclean™ HE for information regarding these
products.

Castrol Brayco® 1720 Plus series oils are intended for use as gear, pump, and lubricating oils where direct or
indirect contact with aggressive chemicals, oxidants, and where low temperatures are routine. The Castrol
Brayco® 1720 Plus series oils can also be used as vacuum pump oils in operations requiring vapor pressures as
low as 10-4 torr. Castrol Brayco® 1720 Plus series oils offer special corrosion protection to iron, copper and a
variety of metals. Perfluorinated fluids, in general, exhibit excellent shelf lives due to their intrinsic inertness.
