Synthetic Zinc-Free Hydraulic Oil

Product code : (HSNZ)

  • Highly compatible with zinc and non-zinc hydraulic oils, easing worries over compatibility issues
  • High viscosity index provides excellent high- and low-temperature performance
  • Outstanding wear protection in industry-standard FZG anti-scuffing and pump-wear tests for long pump and motor life and reduced maintenance
  • Readily separates from water to ease water removal and improve filterability
  • Formulated without heavy metals, making it safer for the environment

Synthetic Zinc-Free Hydraulic Oil



Designed to provide an extra measure of protection compared to other multi-viscosity oils. Features a high viscosity index for superior performance in hot and cold temperatures, reducing the need for seasonal change-outs. Offers excellent wear protection for pumps and motors. Ashless formulation is safer for the environment. Compatible with other hydraulic oils, providing a safe option as a top-off oil.

FIGHTS WEAR

  • Formulated with shear-stable synthetic base oils to protect pumps, motors, valves and other components against wear, even in demanding severe-service conditions.
  • Helps hydraulic systems operate properly and last longer, reducing maintenance.

YEAR-ROUND PERFORMANCE

  • Fights oxidation and maintains viscosity in the presence of elevated heat, ensuring formation of a strong lubricant film.
  • Doesn’t contain waxes inherent to conventional oils for excellent cold-weather fluidity, helping reduce warm-up times, pressure spikes and erratic operation.
