Hydraulic Quick Release Couplings


​Quick release couplings are fitting are used to mate fluid lines with system equipment that requires frequent connecting and disconnecting. They are used in both pneumatic and hydraulic applications to build or discontinue the connection of a fluid pipeline.

​It is well known as quick coupler, quick coupling or quick connect coupling. Quick coupling can be made of stainless steel SS316, carbon steel and brass material for practically every application contingency. ​The fittings size is available from 1/4” to 2”. The working pressure will be determined depending on the body size.



The applications of quick release couplings can be found in many industries. These are essential components in connecting or disconnecting any mechanical lines. The prime objective of such devices is to eliminate fluid leakage.

They are generally corrosion resistant and can be their application is inevitable for a variety of industries.

The Real Applications

You can find the use of quick release couplings in any kind of distribution system such as water, steam, vacuum, air, oil etc. When such systems require frequent connection and disconnection, the use of such a connector is essential for any fluid or system that flows through a line. The disconnection of such lines generally involve considerable amount of fluid loss. You can find straight through, single shut off and double shut off couplings.

They are manufactured with precise specifications to perfectly fit into any system. Designed to answer any kind of problems associated with chemical, pneumatic and hydraulic systems, these devices can connect hoses or delivery lines to permit a smooth flow of the liquid.

The Advantages

The use of quick release couplings can ease and speed up the job, and save a lot of money as well. Its use is as easy as connecting an electrical equipment for operation. As a result, they increase the output of the system and reduce its downtime. These devices reduce the demand of labour in installing and operating such systems. They also eliminate the use of screws and valves in a hydraulic or pneumatic system. Owing to this, the systems making use of such devices save a lot on initial installation and maintenance involved in repairing and replacing the valves and screws. With its use, spillage of costly and dangerous liquids and others fluids can also be prevented. This contributes to a cleaner environment, making way for a safe working environment. This can also minimize and prevent the loss of hydraulic and other fluids that are quite expensive.

Selecting Right Coupling

They are mostly push and pull types and feature a brass body with stainless steel springs. The ball used is also available in steel, the size of these devices vary depending upon the industrial use of each. You should purchase them depending upon their application in your industry. However, do not forget to take into consideration the amount of pressure induced on the fluid system, the size of the system, the fluid type and its flow rate, and the temperature of the fluid.
