Bulk Hydraulic and Suspension Fluids for Equipment and Industrial Systems

At Bulk55 we supply a full range of hydraulic oils and suspension fluids in bulk formats for fleets, agriculture, construction, and industrial applications. Choose anti-wear grades likePresurflo HIVI ISO 32 Hydraulic Fluid, heavy-load formulations like Presurflo HIVI ISO 68 Hydraulic Fluid, and multipurpose tractor options such as Hydratrans Universal Hydraulic Fluid.

We also stock Suspension Fluids engineered for forks, shocks, and struts, ensuring smooth response and consistent damping under load. Bulk55 packaging in pails and drums reduces cost per gallon and keeps operations stocked with fluids that protect equipment from wear and overheating.

Best Hydraulic and Suspension Fluids by Use Case and Business Type

Best anti-wear hydraulic fluid for manufacturing and plant operations

Presurflo HIVI ISO 32 Hydraulic Fluid delivers strong protection and flow stability, which makes it a solid choice for presses, pumps, and machinery in continuous duty cycles.

Best high viscosity hydraulic fluid for construction and heavy equipment

Presurflo HIVI ISO 68 Hydraulic Fluid resists thinning at high temperatures and supports excavators, loaders, cranes, and forestry machines operating in harsh conditions.

Best multipurpose hydraulic fluid for agriculture

Hydratrans Universal Tractor Hydraulic Fluid combines hydraulic, wet brake, and PTO compatibility in one formulation, which simplifies maintenance for tractors and farm fleets.

Best packaging for service centers and distributors

Bulk pails and 55-gallon drums let service centers, industrial plants, and distributors reduce per-gallon cost and ensure steady availability of core hydraulic and suspension fluids.

FAQ

What does AW mean in hydraulic fluids

AW stands for anti-wear. These fluids contain additives that protect surfaces under high pressure and extend the life of pumps, motors, and cylinders.

When should I use ISO 32 versus ISO 68

ISO 32 is thinner and flows better in cold starts and light duty applications. ISO 68 is thicker and performs best under heavy loads, high operating temperatures, or in equipment with higher clearances.

Why use Hydratrans multipurpose tractor fluid

Hydratrans Universal Tractor Hydraulic Fluid is engineered for tractors and agricultural equipment that need a single fluid for hydraulics, wet brakes, and PTOs, which simplifies inventory and reduces cross-contamination risk.

What makes suspension fluid different from hydraulic oil

Suspension fluids are designed with specific viscosity control and foaming resistance for shocks, struts, and forks, whereas hydraulic oils are optimized for pumps, valves, and cylinders in industrial or mobile equipment.

Can transmission fluid be used instead of hydraulic fluid

Even though transmission fluids are technically hydraulic fluids, they are formulated for torque converters and gear sets. Using the correct non-transmission hydraulic oil avoids compatibility issues and ensures proper wear protection.

How often should hydraulic or suspension fluid be replaced

Intervals depend on OEM guidelines, operating hours, and contamination levels. Regular fluid analysis is recommended for hydraulic systems, and suspension fluids should be changed per manufacturer service schedules for optimal damping and protection.

Why buy in bulk

Bulk packaging reduces cost per gallon, lowers packaging waste, and ensures service centers, fleets, and plants always have the right fluid on hand when needed.
