Anti-Varnish AW Hydraulic Oil

Anti-wear, anti-varnish oil that protects against wear and varnish for reliable system performance and service life.


  • Formulated with high-quality anti-varnish additives that interact with the building blocks of varnish and inhibit its formation.
  • Helps keep valves, pumps, seals and other components clean for reliable, long-lasting performance.


  • Resists viscosity loss and promotes formation of a strong lubricating film to help prevent metal-to-metal contact.
  • Protects hydraulic motors, pumps and valves against wear for excellent performance and long life.


  • Formulated with oxidation inhibitors that resist formation of acids and sludge.
  • Resists chemical breakdown in the presence of heat to help keep components clean and functioning properly.
