Phillips 66 - X/C Red Spec Aviation Hydraulic Fluid | MIL-PRF-5606H
Phillips 66® X/C 5606H Aviation Hydraulic Fluids is mineral oil-based, high viscosity index, ashless (zinc-free) anti-wear 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. This fluid is dyed red for identification and leak detection purposes.
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.
