AeroShell Fluid 31 is a ‘synthetic hydrocarbon base’ aircraft hydraulic fluid having excellent low temperature viscosity properties and greatly improved fire resistant characteristics.

AeroShell Fluid 31 is a ‘synthetic hydrocarbon base’ aircraft hydraulic fluid having excellent low temperature viscosity properties and greatly improved fire resistant characteristics.

It contains high technology additives to achieve increased oxidation stability, corrosion resistance, anti-wear, and anti- forming protection. Aeroshell Fluid 31 is superclean filtered to ensure optimum performance in particulate sensitive systems.

AeroShell Fluid 31 is designed for use in aircraft systems, missile, ordnance hydraulic systems using synthetic materials and is suitable for use at operating temperatures from – 40°C to 204°C AeroShell Fluid 31 is a synthetic oil and should not be used in contact with incompatible seal materials, ie natural rubber elastomers.

AeroShell Fluid 31 is dyed red for ease of identification and to assist in the detection of leaks.
