MIL-H-5606A is a mineral oil based hydraulic fluid containing an oxidation inhibitor and a non-zinc anti-wear additive. It is dyed red for identification and leak detection purposes. It may be used in aviation and industrial hydraulic systems where very low temperature flow properties are desired and synthetic rubber seals are in use. It is not recommended for systems using natural rubber seals.

MIL-H-5606A can be used in both aircraft and non aviation hydraulic system with synthetic rubber components. Fluid #4 is intended for use as hydraulic fluid for landing gear retract systems, brakes, oelo stuts , controls, and shock absorbers.

Performance Benefits:

  • Superior low temperature flowability.
  • Good anti-wear protection utilizing a non-zinc anti-wear additive.
  • MIL-H-5606A is dyed red for easy identification and leak detection.
