Zinc-Free Antiwear Hydraulic Fluids For Aerospace & Industrial Applications
Phillips 66 X/C 5606H and X/C 5606A Aviation Hydraulic Fluids are mineral oil-based, high viscosity index, ashless (zinc-free) antiwear hydraulic fluids designed to meet the severe demands of aerospace and industrial applications. They have excellent oxidation resistance and outstanding low-temperature properties for use over a wide temperature range. They provide excellent wear protection for hydraulic pumps and motors, protect hydraulic system components against rust and corrosion, and are resistant to excessive foam buildup that can cause poor or sluggish hydraulic system response.
X/C 5606H Aviation Hydraulic Fluid meets the cleanliness requirements for “super clean” hydraulic fluid for use in modern aircraft hydraulic systems. X/C 5606A Aviation Hydraulic Fluid is recommended for use in hydraulic systems that do not require a “super clean” fluid. Both fluids are dyed red for identification and leak detection purposes.
Very high viscosity index for use over a wide temperature range
Outstanding low-temperature properties
Excellent wear protection
Resists deposit formation and viscosity increase due to oxidation
Protects against rust and corrosion
Good foam resistance
Does not contain zinc or other heavy metals
U.S. Military Specification MIL-H-5606A (obsolete)
X/C Aviation Hydraulic Fluids are recommended for use in non-pressurized systems operating between -54°C and 90°C (-65°F to 194°F), and in pressurized systems operating between -54°C and 135°C (-65°F to 275°F) at pressures up to 3,000 psi.(1) Typical applications include:
Aircraft and missile control systems, autopilots and shock absorbers
Auto wreckers, boom trucks and electrical service equipment (cherry pickers) where all-weather performance is required
Hydraulic systems that require a “super clean” fluid for extended service life and reliability (X/C 5606H)
(1)Note: Do not use these fluids in hydraulic systems with natural rubber elastomers.
Its just brake fluid, but when you need it, the gallon can will be available.

The can arrived dented and leaking. It was in a plastic bag but since UPS tends to tumble turn and throw packages in any conceivable position it leaked out and had about three fourths of the box wet with fluid. Fortunately there was enough fluid to completely flush my aircraft struts.
