MIL-PRF-32014A - Aircraft and Instrument Grease

We perform grease testing according to military specification MIL-PRF-32014, which covers a lubricating grease used in aircraft and missile engines. This lubricating grease is a multipurpose, water-resistant, high-speed grease used in aircraft. This grease is intended as a general purpose aircraft lubricant and is used to lubricate main shaft bearings in missile engines. It provides water resistance and corrosion protection for aircraft and missiles over an extended period, and is operational in a wide temperature range.
