Castrol Braycote 601 EF

Castrol Braycote 601 EF is a smooth, buttery, translucent, off-white, NLGI #2 grease.


Braycote 601 EF 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- c arrying 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. Braycote 601EF with molybdenum disulfide is also available for applications requiring both corrosion and extreme pressure additive.

Braycote 601 EF Temperature Range
-80ºC to 204ºC (-112ºF to 400ºF)

Braycote 601 EF Uses
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.

Braycote 601 EF 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 orga nic
rus t 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.
