Braycote 806 Specification
Braycote 806 meets the requirements of and is qualified to
MIL-PRF-27617F, Type III.
Castrol Braycote 806 is a smooth, buttery, translucent white NLGI #2 grease based on a perfluoroether base oil. It
is thermally stable, nonflammable, and chemically inert to commonly used fuels, solvents and oxidizers. 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 806 Application
Braycote 806 is designed for static and dynamic lubrication of taper plug valves, gaskets and bearings in fuel
systems of aircraft and ground support equipment. It is also suitable for use in the presence of oxygen (LOX/GOX)
as a lubricant for valves, threads, and bearings in aerospace vehicles and supporting equipment. Perfluorinated
greases, such as Braycote 806, exhibit excellent shelf lives due to their inertness.
-30ºC to above 204ºC (-22ºF to above 400ºF).
Braycote 806 Compatibility
Braycote 806 is compatible with all commonly utilized metals, plastics and elastomers. It may be adversely
affected by Lewis Acids catalysts, such as aluminum chloride, at elevated temperatures. Newly exposed rubbing
surfaces of aluminum, magnesium or titanium alloys under certain conditions may react with Braycote 806. Such
systems should be thoroughly evaluated. Surfaces must be well cleaned of organic rust inhibitors prior to grease
application to ensure proper lubrication.
