How to choose Hydraulic Pipe Joint?

Hydraulic Pipe Joint provide compatible threads for connecting hoses in hydraulic systems. They have threads on one end and raised ridges (or barbs) on the other end that grip the inside of hoses to hold them in place and form a seal. They can also be used with worm-gear or worm-drive clamps to provide a tighter seal. Hydraulic Pipe Joint are typically used to create hose assemblies in low-pressure hydraulic applications such as suction lines.

Hydraulic Pipe Joints come in a wide range of types and applications. They are used to connect the hydraulic hose to components like hydraulic cylinders, pipes, tubes, or different types of hydraulic hoses in hydraulic systems.

The different types of Hydraulic Pipe Joints allow the fluid to flow, change its direction, divert, or mix. These fittings should be capable of creating a tight seal and preventing leakage in the application. The Hydraulic Pipe Joints are widely used in hydraulic-powered applications including plumbing, robotics, assembly lines, and heavy equipment.

Selection criteria & points of attention

The following criteria should be considered before selecting the correct Hydraulic Pipe Joint types for your application:

  1. Size: The internal and external diameter of the fittings are two important sizes to consider. These diameters of the fitting should be compatible with the hose diameter. Over or under-sized Hydraulic Pipe Joints can cause leakage or the connection to fail.

  2. Material: The material of the hydraulic fitting should be compatible with the hydraulic fluid and with the operating environment. The most commonly used fitting materials are brass, aluminum, steel, or stainless steel. NBR (Nitrile) O-rings are the most widely used sealing materials.

  3. Temperature: The Hydraulic Pipe Joints should be suitable for your temperature range.

  4. Pressure: The Hydraulic Pipe Joints must be suitable for your pressure range, including the pressure spikes. Operating beyond this range can cause damage to the fittings.

  5. Application: The type of application also determines the fitting type to be used. Tee- or cross- fittings are used for mixing or distribution application.

  6. Assembly: If the hydraulic system requires frequent connecting and disconnecting of the hose or tube, the hydraulic quick-connect fittings can be used. Similarly, hydraulic compression fittings can be used to remove the need for welding or soldering of the fitting. It uses a compression nut to tighten against the ferrule creating a very tight seal. Hydraulic Pipe Joints can be used in areas with high temperatures as welded joints can leak in such environments.

Hydraulic Pipe Joint can connect different hydraulic components to form a closed circuit hydraulic system, it's accessory for connection.


Hydraulic Pipe Joints are used for piping and tubing with hydraulic hoses in the following applications:

  1. Factory applications like assembly lines, presses, robotics, hydraulic power units

  2. Construction and mining equipment

  3. Agricultural equipment

  4. Plumbing applications

  5. Oil and gas industry

Hydraulic Pipe Joint are widely used in military, energy, petrochemical, electric power, ships, automobiles, rail transit.
