MIL-H-5606 -65°F TO +275°F Chemical compatibility with O-rings, rubbers, & plastics

MIL-H-5606 hydraulic fluid is a petroleum based aviation hydraulic oil used in military and aerospace systems designed to operate across a wide temperature range from approximately -65°F to +275°F. It is commonly used in aircraft hydraulic systems including landing gear, braking systems, and flight control mechanisms where reliable high pressure performance is required. When evaluating chemical compatibility, O-rings, rubber seals, gaskets, and plastic components must be selected for compatibility with petroleum hydraulic oils. Proper handling, storage, contamination control, and routine system maintenance help ensure reliable operation and long service life.
