Hydraulic Oils

DR Lubricants HO Series anti-wear hydraulic oils are formulated using premium grade, high quality base oils and are designed to satisfy a wide range of hydraulic requirements. These oils provide excellent oxidative stability and are well suited to deliver superior film strength and anti-wear performance. HO Series oils contain additives that allow the products to remain resistant to degradation and sludge formation, reduce the formation of corrosive materials, cope with moderate water contamination, and provide quick air separation, reducing the problems associated with excess foaming.
