Castrol® Braycote™ 631 RP White Perfluoroether Rust Inhibited Oxygen Compatible Grease - 1.75 lb Can

Castrol® Braycote™ 631 RP is a smooth, buttery, off-white NLGI #2 grease based upon a perfluoroether oil. This grease is nonflammable and is in general chemically inert. It is thermally stable either alone or in the presence of oxygen, has exceptionally low volatility, and has little tendency to form deposits. In addition Braycote™ 631 RP exhibits excellent lubricating properties, good dielectric properties, and shear stability. Castrol Fluoroclean™ X100 and Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to the data sheets for information regarding these products.

Braycote™ 631 RP is designed for static or dynamic service in the presence of fuels and oxidizers. It has been used in gears, ball and roller bearings, electrical contacts, and as a thread and elastomer sealant. It is particularly useful as a lubricant in corrosive or oxygen (LOX/GOX) service and as a plug valve lubricant. This product is compatible with concentrated acids and bases and it does not hydrolyze or oxidize. Perfluorinated greases, such as Braycote™ 631RP, exhibit excellent shelf lives due to their inertness.
