Braycote 815Z
Wide Temperature Range
Perfluorinated Polyether Lubricating Oil

braycote 815Z

Braycote 815Z Description:
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.

Braycote 815Z Temperature Range
-72C to above 204C (-100F to 400F) under normal operating conditions and up to 260C (500F) for brief
periods.

Braycote 815Z Uses:
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. Braycote 815Z  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.

Braycote 815Z Limitations:
Brayco 815Z is compatible with all commonly utilized materials, plastics, and elastomers. It may be adversely affected by Lewis Acid Catalysts such as aluminum chloride at elevated temperatures. Newly exposed rubbing surfaces of aluminum, magnesium, or titanium alloys may react with this product under certain conditions. Such systems should be thoroughly evaluated. Surfaces must be well cleaned of organic rust inhibitors prior to
oil application to ensure proper lubrication.

Braycote 815Z Packaging: QC Lubricants carries Braycote 815Z  in 2 oz and 4 oz (AVDP) disposable polypropylene syringes.
