ISO 68 Hydraulic Fluid

ISO 68 Hydraulic Fluid

Nulon ISO 68 Hydraulic Fluid is suitable for a multitude of hydraulic systems. The unique blend maintains optimum viscosity characteristics over a wide temperature, operating pressure and speed range making it suitable for stationary and mobile hydraulic systems.

Nulon ISO 68 Hydraulic Fluid is blended with a high quality hydro-cracked mineral base fluid and the latest high performance, thermally stable zinc anti-wear additives, along with anti-foam, anti-corrosion and oxidation inhibitors for sustained performance and protection.

The unique high stable zinc anti-wear additive reduces wear on components and protects working surfaces thus reducing equipment down time. The anti-corrosion additives protect the hydraulic system against rust formation due to water contamination or moisture absorption. This coupled with the oxidation inhibitors prevent the formation of harmful sludge, reduces varnish and oil thickening.

Frequently Asked Questions

What is the difference between your Nulon hydraulic fluids, they all list similar specifications?

4 years ago

Nulon hydraulic fluids do carry similar performance specifications but do vary in viscosity. ISO32, ISO46, and ISO68 are a measure of the fluids viscosity, the higher the number the thicker the fluid. Consult your machinery handbook to determine the viscosity recommendations of the equipment manufacturer.
