UNIOIL HYDRAULIC HVI is premium quality hydraulic oil formulated from refined mineral oils and enhanced thermal stability and anti-wear additives, suitable for extreme pressure hydraulic systems, operation in harsh, high temperature conditions.

Characteristic

  • Due to high viscosity index, high shear stability of the viscosity index technology, help to always maintain stable viscosity, suitable for heavy duty hydraulic systems, variable working temperature.
  • Excellent anti-wear and anti-corrosion help to hydraulic system protect and prolong the life of equipment.
  • Good thermal stability and resistance oxidation, prevent the sludge, deposits help to extend the oil life, gives a cleaner system and reduced frequency of filter changes.
