Product Description

Maximum Cleanliness: Synthetic Multi-Viscosity Hydraulic Oil is fortified with anti-varnish additives that chemically react with the building blocks of varnish, inhibiting its formation. It helps hydraulic systems remain clean for solid performance, immediate response and fewer breakdowns.

Excellent Year-Round Protection

Multi-Viscosity Hydraulic Oil's naturally heat-resistant base oils resist thermal break-down and maintain their protective viscosity, allowing formation of a strong lubricating film for excellent wear protection. Because it doesn't contain the waxes inherent to conventional fluids, it flows more readily in cold temperatures, meaning bearings and other components receive almost immediate lubrication at start up, reducing long-term wear and instances of pressure spikes and erratic operation as a result of poor fluidity.

• All-season performance
• Maintains cleanliness
• Promotes maximum fluid life
• Resists foam
• Maximizes energy efficiency

Varnish-Control Technology

Increased heat can cause varnish to form on metal surfaces, including valves, pumps and bearings. Its soft, sticky composition ultimately hardens into a harmful veneer that can reduce fluid flow, plug filters, stick valves and increase friction. Synthetic Multi-Viscosity Hydraulic Oil is fortified with anti-varnish additives that chemically react with the building blocks of varnish, inhibiting its formation. It helps hydraulic systems remain clean and long-lasting.

• Increases convenience and reduces costs due to all-season performance
• Formulated to reduce maintenance costs with anti-wear and anti-varnish chemistry
• Promotes maximum fluid life by resisting viscosity loss and chemical breakdown
• Designed to increase system performance and responsiveness through foam suppression and fast air-release properties
• Helps reduce energy costs due to high-viscosity-index, energy-efficient formulation

Fights Component Wear

Synthetic Multi-Viscosity Hydraulic Oil features a shear-stable formulation fortified with the latest zinc-type anti-wear additives. It meets the stringent viscosity-retention requirements of Parker Hannifin* (Denison*) HF-0 and demonstrates excellent anti-wear performance and compatibility with yellow metals in standardized laboratory and pump manufacturer tests (see below). Synthetic Multi-Viscosity Hydraulic Oil demonstrates excellent protection for pumps, motors, valves and other components against wear.


This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).
