These hydraulic oils inhibit rust and oxidation to protect internal machine components. Also referred to as R&O oils, they are often used in pumps, machine tools, and air compressors in conditions where rust, corrosion, and deposit formation is a concern.

These hydraulic oils are wear-resistant and inhibit rust and oxidation to protect and extend the operating life of internal machine components. Also referred to as R&O oils, they are often used in pumps, machine tools, and air compressors in conditions where rust, corrosion, and deposit formation is a concern.

Extended-life hydraulic oils resist wear and perform twice as long as standard lubricants for high-demand applications where there's a need to extend the time between lubricant changes. Also referred to as EL oils, they are used in hydraulic systems with high-pressure pumps and close-clearance components such as servo valves and numerically controlled (NC) machine tools.
