Aeroshell Fluid 4 Aviation Hydraulic Oil Meeting MIL-H-5606A Specification
Aeroshell Fluid 4 has been discontinued and replaced by Aeroshell Fluid 41
AeroShell Fluid 4 is a mineral-based hydraulic oil with low temperature characteristics that is capable of operating over a wide range of temperatures. This fluid is oxidation inhibited and contains a special anti-wear additive. It is dyed red for identification and leak detection purposes. It also has the following benefits:
- Superior low temperature properties
- Compatibility with synthetic rubber components
- Dyed red for easy identification
- Good anti-wear properties
Applications
- Aircraft applications where a MIL-L-5606A fluid is specified or recommended
- Hydraulic oil systems, particularly those that are subject to a wide variation in ambient operating temperatures
- Winter service for bucket trucks and other portable equipment subject to severe low temperature operation
- Should not be used in aviation applications that call for a MIL-H-5606G type fluid
Specifications
- MIL-H-5606A* (obsolete)
- DEF STAN 91-048 Grade Normal*
