  • Readily biodegradable, ashless, non-zinc formula helps reduce environmental harm in the event of leaks or minor spills
  • Protects against pump and motor wear for maximum component life and reduced maintenance
  • Guards against rust and corrosion to help keep components clean and long-lasting
  • Excellent foam control reduces sponginess and promotes reliable, responsive operation
  • Compatible with common seal materials to reduce leaks and maximize seal life

* Not available in the state of California

Synthetic Biodegradable Hydraulic Oil

Readily biodegradable hydraulic oil formulated with synthetic esters to provide excellent protection against wear, corrosion and foam. Engineered for use in mobile and stationary applications where high biodegradability is required.


  • Premium synthetic ester base oils and high-quality additives protect hydraulic pumps and motors against wear in the toughest operating conditions.
  • Forms a resilient lubricating film on critical parts that withstands stress and increased heat, protecting components and maximizing system life.


  • Provides a high level of biodegradability, which reduces harm in the event of leaks or minor spills.
  • Delivers the ideal combination of excellent protection for equipment and the environment.


  • High-quality oxidation inhibitors resist oxidation in the presence of elevated heat to reduce harmful deposits and promote long oil life.
  • Offers peace of mind that hydraulic systems are protected in severe service, helping reduce maintenance.
