FOUR SEASONS HYDRAULIC FLUID AW
High-Quality Antiwear Hydraulic Oil
Kendall® Four Seasons Hydraulic Fluid AW is a high-quality anti-wear hydraulic fluid developed for use in a wide variety of industrial and mobile hydraulic system
applications. This hydraulic fluid meets the performance requirements of all major hydraulic pump manufacturers and is recommended for use in all types of high-pressure, high-speed hydraulic pumps.
Four Seasons Hydraulic Fluid AW provides excellent wear protection for hydraulic pumps and motors, and protects hydraulic system components against rust and corrosion. With excellent oxidation resistance and thermal stability at high temperatures, this hydraulic fluid minimizes deposit formation and provides long service life. Additionally, this hydraulic fluid has exceptional water-separating properties, which minimizes emulsions and resists excessive foam build up that can cause slow and sluggish responses in hydraulic systems.
