Twin Specialties' line of anti-wear (AW) hydraulic oils are highly refined, premium quality, anti-wear hydraulic oils recommended for use in a wide range of applications. Designed for use in piston, gear pumps, and vane pumps used in industrial and mobile hydraulic systems, Twin's product line of hydraulic oils provide exceptional wear protection for pumps, motors, and other hydraulic system components. All grades have very good oxidation resistance, rust and corrosion protection and foam resistance to provide long service with minimal upkeep. Twin Specialties offers only the most advanced industrial lubricants meet the difficult challenges of effectively balancing performance, strength and durability.

Twin Specialties has multi-grade hydraulic oils designed for year-round service in mobile equipment operating at very low or widely varying ambient temperatures. Products are recommended for use in mobile hydraulic equipment, including cherry pickers, backhoes, shovels, hydraulic cranes and extension ladders. It can be used in stationary hydraulic equipment operating at abnormally low temperatures. Twin's product line of mutil-grade hydraulic oils provide excellent lubricity and wear protection, oxidation and corrosion protection and detergency for system cleanliness.

Twin Specialties' line of high viscosity index (HVI) hydraulic oils includes supreme quality anti-wear hydraulic oils specially developed for applications subjected to wide range of temperature or where small viscosity change with fluctuating temperature is needed. They are formulated with severely hydro-processed Group II base oils, a highly shear stable polymer and an advanced additive system to meet the stringent requirements of modern hydraulic systems using high pressure high output pumps and critical requirement of other hydraulic system. These HVI hydraulic oils are employed in hydraulic systems of excavators, cranes and hydrostatic drives subjected to most severe outdoor operating conditions, and hydraulic systems operating under high pressures and requiring high degree of load carrying capability and anti-wear protection. These oils are recommended for use in outdoor mobile equipment that is used year-round such as cranes, bucket trucks (cherry pickers), cranes, aerial lifts, and the like.

Twin Specialties line of detergent hydraulic oils are highly refined, premium, anti-wear hydraulic oils with a unique detergency/dispersant package developed to meet the requirements of high pressure hydraulic systems. They are designed for use in industrial and mobile hydraulic systems where component cleanliness is paramount and where deposit control is critical. Detergent hydraulic oils are particularly recommended for use in hydraulic systems on mobile, industrial, or marine equipment, machine tools, elevators, floor jacks, hoists, winches, air tools and lubers, lifts, and many other hydraulic applications. They can also be used in applications that experience high levels contamination, such as hydraulic units in off-road equipment and trucks.

Twin Specialties' line of ashless hydraulic oils are highly refined, ashless, anti-wear hydraulic oils developed to meet the requirements of high pressure hydraulic systems.

Twin Specialties' line of fire resistant hydraulic oils include both water-glycol based and polyol-ester based fluids. These oils are excellent for applications that require a high degree of lubricity and fire resistance such as die-casting machines, forging machines, furnace doors, and mining equipment. The oils also provide protection against rust and vapor phase corrosion.
