Product Information

AeroShell Fluid 41 contains additives which provide good low temperature fluidity, anti-wear, oxidation-corrosion inhibition and shear stability. In addition metal de-activators and foam inhibitors are included in this high viscosity index fluid to enhance performance in hydraulic applications, making it capable of wide temperature range operation.


AeroShell Fluid 41 is intended as a hydraulic fluid in all modern aircraft applications requiring a mineral hydraulic fluid. AeroShell Fluid 41 is particularly recommended where use of a "superclean" fluid can contribute to improvements in component reliability, and can be used in aircraft systems operating unpressurised between 54°C to 90°C (-65°F to 194°F) and pressurised between -54°C to 135°C (65°F to 275°F).

AeroShell Fluid 41 should be used in systems with synthetic rubber components and must not be used in systems incorporating natural rubber.

AeroShell Fluid 41 is compatible with AeroShell Fluids 4, 31, 61 and LGF. Chlorinated solvents should not be used for cleaning hydraulic components which use AeroShell Fluid 41. The residual solvent contaminates the hydraulic fluid and may lead to corrosion.

Due to its properties, it is also used in several industrial applications.
