AW hydraulic oil is specially formulated with only the finest quality, hydrotreated, high viscosity index, paraffinic base oils and the most advanced additives. AW is a premium hydraulic oil designed to meet the requirements of major pump manufacturers for the protection of hydraulic pumps. These oils have high oxidation stability that yields dramatically longer service life than conventional hydraulic fluids. Metal-to-metal contact is kept to a minimum, helping extend equipment life. Designed for use in vane, piston and gear-type pumps of mobile and stationary equipment. Especially well-suited for applications which exceed 5,000 psi such as axial piston pumps.
