AeroShell Fluid 4 is dyed red.


Main Applications

AeroShell Fluid 4 is intended for use as a hydraulic fluid inundercarriage retraction mechanisms, flap jacks and control
mechanisms, brakes, shock absorbers, automatic pilots, oleo legs, tail wheels, servo units, etc. AeroShell Fluid 4 is also

AeroShell Fluid 4 is compatible with AeroShell Fluids 31, 41,51, 61 and 71, although it is not recommended that AeroShell
Fluid 4 is used in systems that require the use of a super clean fluid nor should it be mixed with super clean fluids
