Applications
AeroShell Fluid 41 is intended as a hydraulic fluid in all modern aircraft applications requiring a mineral hydraulic fluid 鈥� commonly in landing gear hydraulic systems. 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掳颁 to 90掳颁 (-65掳F to 194掳F) and pressurised between -54掳颁 to 135掳颁 (65掳F to 275掳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 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, AeroShell Fluid 41 is also used in several industrial applications.
