Description
Castrol Braycote 601 EF is a smooth, buttery, translucent, off-white, NLGI #2 grease. Its base oil (Castrol
Brayco® 815Z) is a perfluorinated polyether, with exceptional chemical resistance, extremely low volatility, and a
wide temperature service range. The grease is non-toxic, nonflammable, and does not use any
chlorofluorocarbons (CFC's) during product manufacture. This product exhibits unusually high load-carrying
capabilities as measured by the Four-Ball EP Test, and contains a rust and corrosion inhibitor for extra component
protection. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to
the data sheets for these products for information regarding these products.
Application
Braycote 601 EF is designed to operate in the presence of rocket fuels and oxidizers and high vacuum. It is
frequently used in space applications including the Space Shuttle and satellites. It should also be considered in
any application where a hostile chemical or extreme environmental conditions would preclude the use of an
ordinary grease. Typical applications include ball and roller bearings, gears, and as an assembly lubricant for O-
rings and elastomers. Perfluorinated greases, such as this product, exhibit excellent shelf life due to their intrinsic
inertness.
Typical Characteristics
Limitations
Braycote 601 EF is compatible with most 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 and 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 grease application to insure proper lubrication. This product is not recommended for use in applications
under high vacuum with loads exceeding 100,000 psi for extended periods of time.
Packaging
Braycote 601 EF is available in 2 oz and 4 oz (AVDP) disposable polypropylene syringes, 1 lb jars, and 1.75 lb
cartridges. A specially prepared "micronic", ultra clean version is available upon request.
