AeroShell Fluid 3 General Purpose Mineral Lubricating Oil - Gallon Can

AeroShell Fluid 3 General Purpose Mineral Lubricating Oil MIL-PRF-7870 is recommended for the general lubrication of aircraft parts such as pulleys, cables, camera mechanisms, linkage pins, shaft joints and more. The light oil features good low temperature characteristics and a low freezing point making it ideal for northern climates. The lubricant is inhibited against oxidation and corrosion, plus it has a low viscosity and good resistance to evaporation. Because it is a thinner lubricant, it should be applied b means of an oil can or brush. The ideal operating temperature range is -54°C to +121°C.

APPLICATIONS

AeroShell Fluid 3 is recommended for general lubrication of aircraft parts that require a light oil, e.g. hinges, pivot joints, shaft joints, linkage pins and bearings, pulleys, cables, camera mechanisms, radio and radar gear and instruments. AeroShell Fluid 3 is normally applied by means of an oil can or brush. For this reason it is also described as 'an oilcan lubricant'.

Operating temperature range of AeroShell Fluid 3 is -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; however in this case care should be taken to ensure that there is no incompatibility between AeroShell Fluid 12 and seals, paints etc.
