AEROSHELL® Fluid 3 General Purpose Mineral Lubricating Oil
The AEROSHELL® Fluid 3 is a general purpose mineral lubricating oil recommended for general lubrication of aircraft parts that require a light oil with good low temperature characteristics and a low freezing point. It is inhibited against oxidation and corrosion. It is a relatively low viscosity product with good resistance to evaporation. Recommended for general lubrication of aircraft parts requiring a light oil, e.g. hinges, pivot joints, shaft joints, linkage pins and bearings, pulleys, cables, camera mechanisms, radio and radar gear and instruments. The AEROSHELL® Fluid 3 is normally applied by means of an oil can or brush. Operating temperature range: –54°C to +121°C. For high temperature applications where no provision is made for frequent re-lubrication the synthetic oil, AEROSHELL® Fluid 12, should be used in place of the mineral oil, AEROSHELL® Fluid 3 provided that proper attention is given to any incompatibility issues between AEROSHELL® Fluid 12 and seals, paints etc.
The AEROSHELL® Fluid 3 complies with the following specifications : MIL-PRF-7870D, DEF STAN 91-47, O-142, OM-12.
AEROSHELL® Synthetic Ester Oil 12
The AEROSHELL® Fluid 12 is a synthetic oil used for general aircraft lubrication as well as for aircraft gyro instrument gimbal bearings, separately lubricated high speed turbines and compressors, aircraft air cycle equipment and electronic equipment. It is oxidation and corrosion inhibited, and possesses good high and low temperature characteristics. Particularly suitable when an oil with a low evaporation rate is required at high and low temperatures. It should not be used in contact with incompatible seal materials such as neoprene or natural rubber. Suitable seal material include Fluorocarbon (Viton). Fluid 12 may also affect certain paints and plastics and it is recommended that components are evaluated for compatibility if there is any question.
Applications:
- for general aircraft lubrication as well as for aircraft gyro instrument gimbal bearings, separately lubricated high speed turbines and compressors, aircraft air cycle equipment and electronic equipment
- for use when an oil with a low evaporation rate is required at high and low temperatures
