How many types of hydraulic joints?

Joints play a huge role in hydraulic systems, but the majority of users do not know enough about hydraulic joints. As a professional manufacturer of hydraulic fittings, we will introduce the basic knowledge of hydraulic joints to you.

Principle of hydraulic joints

Quick-change joints are divided into two categories: one-way valves and check valves. The principle of the joint with the check valve is a check valve end connected to the air source. When the check valve is disconnected, the check valve automatically closes. After connection, the active end casing opens the check valve. Self-locking is the use of embedded in the groove of the steel ball, while through the "cone-cylinder" sleeve will lock the steel ball.


Works, Applications and Types of Hydraulic Joints

Application of hydraulic couplings

Hydraulic fittings are used in hydraulic systems, and their role is to connect the high-pressure oil pipe and high-pressure oil pipe parts. The various types of fittings required to manage the hydraulic or pneumatic connections of various fluid power components are hydraulic fittings. The purpose of use is mainly to connect the pipe to the hydraulic system. The bearing interface has a seal to prevent leakage.

Hydraulic coupling construction

Connectors are used to connect components of fluid power systems. Structurally, there are at least two ports, in addition to the plug and cap are necessary. The connector type forging connected with the system components is the port end, and the end connected with the hose rigid pipe fitting is the pipe end.

JIC 37⁰ Flares

The Joint Industry Conference (JIC) fitting is the most common type of hydraulic connection. It consists of a parallel thread and a 37⁰ cone on the fitting end that can be attached to a flare pipe or hose fitting.

O-Ring Face Seals

O-ring face seals have a flat sealing surface that contains embedded seals for use with flanged pipe or hose fittings. The flat sealing surface reduces the risk of over-torque and the captured seal prevents leakage.

O-Ring Boss

The SAE straight thread O-Ring Boss (ORB) is the same thread as the straight thread 37⁰ JIC Flare. The difference is in the way each thread is sealed.

Inch Compression

Inch compression fittings are a type of bite type fitting for hydraulic hoses with very limited hose connections of this type. The fitting can be assembled in the field to hydraulic hard pipe with minimal tooling.

NPT Pipe Threads

NPT pipe threads are your traditional tapered thread fittings that have been in use for 100 years. They are available in low-pressure black iron and brass, as well as high-pressure steel and stainless steel. This type of connection is used in pneumatic and process systems as well as hydraulic systems.

DIN Metric 24⁰ Bite Type

This is the most common style of hydraulic coupling in Europe. As such, this type of hose coupling is available in a full range for use with metric sized piping. Newer versions of this fitting style feature captured elastomeric seals on the mating surfaces to provide better sealing and reusability.

Four-Bolt Flange

4-bolt flange connections conforming to SAE J518 and ISO 6162-1 and -2 are proven, leak-free connections that are especially suited for larger sizes, higher pressures, and assemblies in confined spaces.
