Tribolube-57 is a wide temperature range grease especially useful in vacuum and other systems where non-reactivity with chemicals, strong acids and oxidizers, fuels, and solvents is required. Although this lubricant is very inert, newly exposed rubbing surfaces of aluminum and magnesium may react with the greases under certain conditions. Tribolube-57 is available with an extreme pressure additives designated by the letters MS as well as three different corrosion inhibitors designated by the letters RPA, RPB, & RPC. Please consult with an ALI lubrication engineer to select the correct one for your application.
