Duragard® HI-TEK ULTRA HVI-46 HYDRAULIC FLUID is a premium quality, HVI-MV blended mineral oil based hydraulic fluid with excellent low and multi-temperature characteristics that is capable of operating over a very wide operating temperature range, from arctic conditions to desert heat. This fluid contains a robust additive package to significantly improve oxidation resistance and special anti-wear additives to protect and prolong equipment life. The formulation uses a proven anti-wear additive system that is effective in reducing wear for high-pressure vane, piston and gear pumps. Meets OEM stringent requirements for severe conditions while improving pump and valve performance.

Duragard® HI-TEK ULTRA HVI-46 HYDRAULIC FLUID has excellent water separation, rust and corrosion prevention, oxidation stability, and anti-foam properties. The true multi-viscosity, broad temperature feature allows even and continuous power transmission over a wider temperature range with increased accuracy and reduces torque. Suitable for use in hydraulic equipment operating in very cold conditions while maintaining excellent fluidity. Compatible with synthetic rubber components.
