2 oz. perfluoropolyether grease.
CHRISTO-LUBEŽ MCG111 is a wide temperature range, perfluoropolyether grease which was developed for use in systems where non-reactivity with harsh chemicals including strong acids and oxidizers, fuels, solvents, etc. is an important factor. The grease is suitable for use in applications including electrical contacts, valves, threads, screws, bearings and in systems employing elastomeric and plastic seals, gaskets and o-rings. Although CHRISTO-LUBEŽ MCG 111 is very inert, newly exposed rubbing surfaces of aluminum and magnesium may react with the grease under certain extreme conditions. CHRISTO-LUBEŽ MCG 111 meets the specification requirements and has been qualified under Military Specification MIL-PRF-27617F, Types I, II, and III.
