Aeroshell Fluid 31 Pail

$759.00 inc. GST per 18.9 L pail

AeroShell Fluid 31 is a synthetic hydrocarbon based aircraft hydraulic fluid with greatly improved fire resistance characteristics when compared with conventional petroleum products. (Image shows a can not a pail)


AeroShell Fluid 31 has a specially designed base stock which imparts a relatively high flash point, excellent low temperature properties and good oxidation and thermal stability. In addition it is formulated with high technology additives to provide oxidation and corrosion resistance, antiwear, and anti-foaming protection. AeroShell Fluid 31 is superclean filtered to ensure optimum performance in particulate monitored systems. The useful operating temperature range is –40 to +205°C.

Main applications

Aeroshell fluid 31 is recommended for use in aircraft, ordnance, and missile systems operating from -40°C to +205°C. This fluid should be considered fo use in auto pilots, shock absorbers, brakes, flight control systems, hydraulic servo-controlled systems and other systems using synthetic elastomer seals. An increasing number of aircraft manufacturers now recommend this type of fluid in aircraft hydraulic systems in preference to mineral hydraulic oils. This move has been prompted by the need to use fluids with better fire resistant properties.

Aeroshell fluid 31 is also approved for use in the Honeywell (formerly Garret) cooling turbine (cabin air compressors). Increasingly this type of hydraulic fluid is being adopted for use in hydraulic systems for military aircraft in place of mineral hydraulic fluids.

Aeroshell fluid 31 is a synthetic hydrocarbon oil and should not be used in contact with incompatible seal materials.

Aeroshell fluid 31 is compatible with Aeroshell Fluids 4, 41, 51, 61, and 71 and can be used in systems designed to operate with MIL-PRF-5606, MIL-PRF-6083, MIL-PRF-87257 and MIL-PRF-46170 fluids.

Chlorinated solvents should not be used for cleaning hydraulic components which use Aeroshell fluid 31. The residual solvent contaminates to hydraulic fluid and may lead to corrosion.
