Braycote 804 Specifications
Braycote 804 meets the requirements of and is qualified to MIL-PRF-27617F, Type I.
Temperature Range
-54ºC to 149ºC (-65ºF to 300ºF).
Braycote 804 Applications
Braycote 804 is designed for static and dynamic lubrication of taper plug valves, gaskets and bearings in fuel systems of aircraft and ground support equipment.
Braycote 804 is also suitable for use in the presence of oxygen (LOX/GOX) and other highly oxidative materials as a lubricant for valves, threads, and bearings in aerospace vehicles and supporting equipment. Perfluorinated greases, in general, exhibit excellent shelf lives due to their intrinsic inertness.
Braycote 803 Compatibility
Braycote 804 is compatible with all commonly used plastic, elastomer and metallic materials of construction. Braycote 804 may be adversely affected by Lewis Acids such as aluminum chloride, at elevated temperatures. Rubbing surfaces of aluminum, magnesium or titanium alloys may react with Braycote 804 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.
