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. It is designed for static and dynamic lubrication of taper plug valves, gaskets and bearings in fuel systems of aircraft and ground support equipment, and is also suitable for use in oxygen (LOX/GOX) as a lubricant for valves, threads and bearings in aerospace vehicles and supporting equipment. It is removed with Brayco IC X-100. Service temperature is −30 °C to above 204 °C. It meets and is qualified under MIL-PRF-27617G Type III.
