Hydraulic Oil

United MV (multi-viscosity) Hydraulic Oils are all-season hydraulic lubricants engineered for applications within a wide temperature range. These oils are formulated with rust and oxidation inhibitors, anti-wear agents and anti-foam additives. United MV Hydraulic Oils have good water separation capabilities so that contaminant water may be drained from the reservoir when the machine is at rest. In-plant filtration systems ensure ISO cleanliness standards during blending and packaging, providing a clean product for hydraulic systems.

With a pour point of –85 °F, United Arctic Blue Hydraulic Fluid is ideally suited for hydraulic equipment operating in extreme cold temperatures while also providing good year-round protection. This product is recommended for bucket trucks (cherry pickers), snow plows, garbage trucks, industrial and mobile equipment, and most hydraulic equipment where there is a wide range of operating temperatures and reliability is critical. United Arctic Blue Hydraulic Fluid has a high dielectric strength for use in electrical service or tree trimming bucket trucks

United Industrial Hydraulic Oils are formulated with advanced low-zinc anti-wear additives and also provide rust and oxidation protection in hydraulic systems. This additive system is balanced with high quality base oils to deliver an effective combination of anti-wear, demulsibility, filterability, rust protection, oxidation resistance and foam resistance properties.

It meets the performance requirements of conventional anti-wear hydraulic oils in severe applications, while providing additional safety in case of a leak or discharge to the environment.

United Hydraulic Plus ISO 32, 46 and 68 is formulated with hydro-processed Group II base oil combined with a low-zinc, universal anti-wear hydraulic oil additive. It provides premium anti-wear, rust and oxidation performance. The additive system is balanced with high quality base oil to ensure the best combination of anti-wear, filterability, rust protection, oxidation resistance and foam resistance properties. The hydro-processed Group II base oil provides improved oxidative and thermal stability, as well as enhanced dispersancy.

United Synthetic Anti-Varnish MV (Multi-Viscosity) Hydraulic Oil is formulated with a high viscosity index for all-season use in cold and hot temperature environments and is engineered to protect against varnish and foam in hydraulic systems. The high viscosity index not only provides excellent extreme-temperature properties but also improves the likelihood of product consolidation.

United R&O Turbine Hydraulic Oil ISO 32, 46, 68 and 100 is designed for use in many applications that require protection against rust and oxidation, but do not require anti-wear or extreme pressure additives. It may be used for lightly loaded plain and anti-friction bearings, electric motors, machine tools, air compressors and circulating systems that require rust and oxidation inhibited oil. United R&O Turbine Hydraulic Oil is formulated to meet lubrication requirements of steam and gas turbines and many hydraulic applications. It is also recommended for service in most axial piston pumps and high pressure and high output systems. United R&O Turbine Hydraulic Oil’s low ash level permits its use in automated machine tools and mobile or stationary applications that have stringent filterability requirements.

United Synthetic Hydraulic Oils are formulated for use in severe-service, low and high pressure, mobile or stationary hydraulic systems. These full synthetic hydraulic oils feature outstanding thermal stability and cold-flow properties. United Synthetic Hydraulic Oils resist the formation of varnish that contributes to valve sticking and improves hydraulic efficiency in cold temperatures.

United MV (Multi-Viscosity) Zinc Free Hydraulic Oil ISO 46 is an exceptional multi-grade, anti-wear, high viscosity index hydraulic oil. This oil is formulated specifically for use in equipment that is operating over a wide range of temperatures and where oil with dielectric properties is required. It is recommended for use in Hitachi, John Deere and other off-road equipment. These oils have a balanced additive combination of pour point depressants and shear stability viscosity index improvers which make them suitable for operating in outdoor mobile equipment under cold start-up operating conditions. In addition to its excellent low-temperature characteristics, United MV Zinc Free Hydraulic Oil 46 will also maintain sufficient body film strength to lubricate at the warmer operating temperatures found in many operations.

United Premium Hy Vis 5W-20 Hydraulic Oil delivers excellent low temperature start-up capability, coupled with high temperature viscosity stability. Equipment operating over a broad temperature range can benefit from year-round use of United Premium Hy-Vis 5W-20 Hydraulic Oil. It is formulated with a balanced additive package and shear stable viscosity index improver to maintain sufficient body film strength to lubricate at the warmer operating temperatures found in many operations.

United MV Extreme Hydraulic Oil ISO 32 is a multi-grade hydraulic lubricant engineered for extreme temperature ranges. The low pour point of -58° F enables this fluid to flow quickly in extreme cold climates, avoiding pump cavitation that results in pump wear. The high viscosity index of this fluid also addresses extreme hot climates and operating temperatures, thinning out less at high temperatures than typical hydraulic fluids.

United Off Road Hydraulic Plus SAE 10 and 30 is formulated with premium quality Group II base oils combined with a high zinc universal anti-wear additive package. It also contains additives to provide rust and oxidation protection, foam resistance and it contains emulsifiers designed to disperse water and improve filterability. This additive system is balanced with high quality base oil to provide excellent oxidative and thermal stability. United Off Road Hydraulic Plus is excellent for high heat applications.

United Special Hydraulic Anti-Shudder Fluid is a multi-grade hydraulic lubricant engineered for extreme temperature ranges. The low pour point enables this fluid to flow quickly in extreme cold climates, avoiding pump cavitation that results in pump wear. The high viscosity index of this fluid addresses the extreme hot climates and operating temperatures, thinning out less at high temperatures than typical hydraulic fluids.

United Syn Hydraulic XT ISO 46 is a full synthetic, anti-wear hydraulic oil formulated for all-season performance. Through its synthetic base oil, a high performing viscosity index improver and a premium additive package, United Syn Hydraulic XT is built to handle the extreme conditions commonly found within construction and forestry applications.

United Synthetic Biodegradable Hydraulic Oil ISO 46 is a readily biodegradable hydraulic oil formulated with synthetic esters to provide excellent protection against corrosion, wear and foam. It is engineered for use in mobile and stationary applications where high biodegradability is required.
