NATIONAL HYDRAULIC OIL VH 15-32-46-68-100
National Hydraulic Oil VH series is anti-wear oil blended with high quality base oils incorporated with special additives that impact superior viscosity / temperature characteristics. They have a very high viscosity index and low pour points to provide fluidity at sub-zero temperatures, and they remain suitable for widely varying ambient temperatures.
Benefits
- Very low viscosity variation with temperature.
- High shear stability.
- Oxidation resistant.
- Excellent filterability.
- Efficient anti-wear performance.
- Rust and corrosion protection.
Applications
National Hydraulic Oils VH Series is especially suited for hydraulic systems which are subjected to extremes of temperature. Suitable for Hydraulic and Fluid Power Transmission system subjected to wide variation in temperature of where low viscosity change with fluctuating temperature is required. They are available in a wide range of viscosities to meet a variety of design and operating requirements.
