Castrol Brayco 815Z is a clear water white perfluorinated polyether based fluid. It is virtually inert, compatible with
rocket propellants and oxidizers, is unaffected by ultraviolet, cosmic radiation, or high vacuums. It has an
exceptionally high viscosity index and low volatility, and has little tendency to form deposits. This product is highly
recommended for use in applications at low temperature extremes and in high vacuum. It exhibits excellent
lubricating properties, good dielectric properties, excellent shear stability, and low toxicity. Castrol Fluoroclean™
X100 or Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to the data sheets for information
regarding these products
Application :
Brayco 815Z is essentially insoluble in current fuels and oxidizers, as well as in most organic solvents. This
product is intended for use in extreme environments, and has been used successfully in many space missions
and in sensitive electronic equipment. It is particularly suited for those applications where extreme vacuums and
wide temperature variations are common. Perfluorinated fluids, in general, exhibit excellent shelf lives due to their
intrinsic inertness.
