Hydraulic Components
Category Selection
Hydraulic systems are fluid power systems that use incompressible fluid (typically oil) at high pressures, allowing for actuation with a much higher force and torque. This provides very precise positioning in actuators with smooth steadiness throughout the motion. While hydraulic systems can be complex, it is possible to build a durable, powerful system for many industrial applications with a few basic components:
- A fluid reservoir is a tank that holds the hydraulic fluid, protects it from contaminants, and helps keep it cool
- Pumps generate the flow of hydraulic fluid so that it can be used for producing energy and performing tasks
- Filters remove contaminants from hydraulic fluid to prevent seal breakdown and heat buildup from unnecessary friction
- Valves control the flow of fluid throughout the system and direct the fluid to where it is needed. Control valves are typically available in manual, piloted, and solenoid operated styles
- Hydraulic actuators translate the flow of fluid into mechanical motion or torque. Hydraulic cylinders are a commonly used linear actuator, while hydraulic motors can be used to convert the flow of hydraulic fluid into rotational motion
- Hoses provide a path for fluid to flow between devices; adapters connect hoses to valves, power units, manifolds, and actuators
Hydraulic power units are self-contained assemblies that include a reservoir, pump, and filter. These units offer utmost convenience and are designed to deliver reliable hydraulic power with various flow rates and pressure ratings available. HPU heat exchangers can be used to reduce heat buildup and help extend the life of HPU fluid and the overall hydraulic system.

Hydraulic Power Units
Hydraulic power units include a reservoir, pump, filter, and many other combined accessories integrated into one unit. They provide proper pressure and volume for reliable operation of hydraulic systems.
- Includes properly sized motor
- Integrated reservoir
- Fully contained unit includes all controls and gauges
Heat Exchangers for HPUs
Heat exchangers for hydraulic power units increase the life of a hydraulic system by allowing fluid to operate at a lower temperature.
- Includes all hardware for installation
- Available for T-series HPUs only
- Improves life of overall system
Hydraulic Power Unit Accessories
Several accessories are available for hydraulic power units and associated valves to help complete the unit's installation, maintain the unit, and replace damaged components.
- Unloader valves
- Valve adapters
- Mounting bolts
- Replacement solenoid coils
- Hydraulic fluid filters
Hydraulic Solenoid Valves
Hydraulic solenoid valves direct the flow of fluid throughout the system, and control the motion of hydraulic actuators, such as cylinders.
- 4-way, 3-position NFPA D03 and D05 patterns
- Four available center configurations for D03 versions; two available center configurations for D05 versions
- 120 VAC or 24 VDC double solenoids
Hydraulic Cylinders
Hydraulic cylinders are linear actuators that convert the flow of pressurized hydraulic fluid into linear motion and force. They produce higher force than a pneumatic cylinder, with greater flow control and smoother motion.
- Interchangeable with other popular brands of NFPA hydraulic cylinders
- Bore sizes up to 4 inches
- Wide selection of stroke lengths up to 24 inches
- All models are double acting
- Large selection of mounting bracket styles and hardware to ensure a perfect fit
- Made in the USA
Hydraulic Hose Assemblies
New!
Hydraulic hoses allow fluid to flow from power units and pumps to cylinders, actuators, and manifolds. Hoses are often fabricated at a work site, but these hydraulic hose assemblies are already cut to length and terminated with female JIC swivel fittings on both ends. All assemblies meet SAE 6149-3.
- Heavy-duty hydraulic hose assemblies
- High-flex hydraulic hose assemblies
Hydraulic Adapters
New!
Hydraulic adapters are used to connect hydraulic hoses to valves, actuators, or manifolds. All models are steel-plated and meet SAE J514 and 6149-3.
- O-ring boss to Straight JIC, Elbow JIC, elbow O-ring boss, or straight O-ring boss reducer adapter styles
- Elbow JIC to JIC adapters
- Straight JIC to flat face adapters
