Phillips 66 Hydraulic Oil AW/D ISO Grade 32
Categories: Fluid; Lubricant

Material Notes: Hydraulic Oil AW/D is a high-quality antiwear hydraulic oil developed for use in industrial and mobile hydraulic systems where component cleanliness is critical. It is formulated with a dispersant/detergent additive to help keep the hydraulic system clean and free of deposits. Hydraulic Oil AW/D is formulated to provide excellent wear protection for hydraulic pumps and motors, to protect hydraulic system components against rust and corrosion, and to maintain excellent hydraulic system cleanliness. It has good oxidation resistance and thermal stability at high temperatures to minimize deposit formation and provide long service life. It has high dispersancy-detergency to keep close-tolerance servo valves clean and freely operating for maximum system efficiency, and is resistant to excessive foam buildup that can cause poor or sluggish hydraulic system response. Hydraulic Oil AW/D is recommended for use in all types of high-pressure, high-speed hydraulic pumps. However, it should not be used in hydraulic systems where good water separation is required, since the dispersant/detergent additive will emulsify water and hold it in suspension.
