Complete Line of Hydraulic Accessories

Numerous hydraulic accessories are available, and each has particular uses. Some are best used for controlling fluids, while others control pressure or flow rate. Therefore, it’s crucial to understand their usage and application to determine what a hydraulic system needs to perform optimally while ensuring its functionality is not impaired.

Some of the accessories we provide are:


Industrial hose & hydraulics are a vital part of the hydraulic system that carries pressurized fluids from one component to another. They are available in different materials and sizes, each with unique functions and capabilities. Diverse industries rely on industrial hydraulic hoses for varying reasons, which highly depend on the equipment or machine used. We provide hoses that handle multiple temperature ranges, pressure ratings, and media.

Common applications of hydraulic hoses include:

  • Construction: Enables the functionality of heavy-duty equipment like excavators, loaders, and bulldozers.
  • Agriculture: Used in tractors, combines, sprayers, and other machinery.
  • Mining: Essential for operating heavy mining equipment, such as drills, shovels, and haul trucks.


Fittings are necessary to connect hoses to other components such as valves, pumps, cylinders, etc. A hydraulic compression fitting ensures that the connection within hydraulic systems is leak-free while eliminating the need for welding or brazing of fittings since it utilizes a compression nut to tighten the ferrule. Thus, a hydraulic compression fitting creates an ultra-tight seal for high-pressure applications such as construction, mining, and industrial machinery.

Common applications of hydraulic fittings include:

  • Factories: Factory applications like robotics, assembly lines, hydraulic power units, and presses.
  • Plumbing: Fittings are vital for industrial plumbing applications, such as water, oil, and gas transportation.
  • Hydraulics systems: Fittings are used in various hydraulic systems like power steering, brakes, and fuel delivery.


A hydraulic pressure gauge is a crucial device in every hydraulics system. It’s used to gauge the hydraulic pressure and display it within the system, allowing operators to monitor and adjust system performance. The gauge’s readings are vital as they indicate if the system is functioning correctly or if any issues need to be addressed. Without a pressure gauge, it would be challenging to determine the state of the hydraulic system, leading to potential failures and downtime.

Reasons to use a hydraulic pressure gauge:

  • Visibility: The gauge will tell you if a problem within the system must be attended to before it escalates.
  • Prevents overloading: With a pressure gauge, you can monitor the system’s pressure and avoid any potential damage caused by excessive pressure.
  • Troubleshooting: A gauge can help you identify the root cause of any issues within the system, making it easier to troubleshoot and fix.

Heat Exchangers

Heat exchangers are necessary for maintaining proper temperature levels in hydraulic systems. They regulate fluid temperature by transferring heat from one medium to another, preventing overheating and potential system failures. The media may be a gas, liquid, or a combination of both, separated by a wall to prevent mixing or direct contact. Its functions include removing heat from hydraulic power units, maintaining fluid viscosity, and reducing wasted energy.

Common applications of hydraulic fittings include:

  • Industrial machinery: Used in various industrial machinery, such as injection molding machines, presses, and hydraulic power units.
  • Cooling systems: Heat exchangers are crucial for cooling systems used in engines, transmissions, and other mechanical systems.
  • Hydraulic system maintenance: Regularly maintaining the temperature of hydraulic fluids is essential for maximizing system performance and longevity.


A hydraulic reservoir holds the fluid needed to supply a system. It also includes a reserve to compensate for any fluid that may leak or bleed from the system. A reservoir is necessary to maintain consistent fluid levels, transfer heat, allow contamination to drop out of the fluid and settle at the bottom to prevent it from recirculating and damaging the entire system, and enable air bubbles to come to the surface to dissipate.

Common applications of hydraulic reservoirs include:

  • Marine equipment: Boats and other marine vessels require hydraulic reservoirs to operate their steering, navigation, and propulsion systems.
  • Heavy-duty machinery: Industrial equipment like cranes, lifts, and presses rely on hydraulic reservoirs for smooth operation.
  • Aerospace industry: Hydraulic reservoirs are used in the aerospace industry for functions like landing gear extension/retraction.


Another crucial component in every hydraulic system is hydraulic control valves. These are mechanical devices that regulate the flow of fluid within a hydraulic circuit or system. Some of its primary functions include maintaining system pressure, directing pressurized fluid to different components, controlling the direction of flow, and regulating the flow rate of a particular area. A malfunctioning valve can cause severe issues within a hydraulic system, so it’s crucial to use high-quality valves suitable for your specific system.

Common applications of hydraulic control valves include:

  • Construction equipment: Valves are used in various construction equipment such as cranes, excavators, and forklifts.
  • Automotive industry: Hydraulic valves are used in automotive applications like power steering, brakes, and transmissions.
  • Agriculture machinery: Tractors, harvesters, and other agricultural machinery require hydraulic control valves.


An important component in any hydraulic system is the hydraulic oil filters. These remove damaging particulates by forcing the hydraulic fluid through a porous filter. The filter element catches the contaminants and stops them from entering the fluid flow. Therefore, it can’t damage other components downstream.

Common applications of hydraulic oil filters include:

  • Continuous operation systems: Hydraulic oil filters are essential for continuous operating systems, such as irrigation, road construction, and mining equipment.
  • Sensitive systems: Certain hydraulic systems require high levels of filtration to prevent damage to sensitive components.
  • Maintenance: Regularly replacing or cleaning the filter element is crucial for maintaining optimal performance and longevity of the hydraulic system.
