The Basics of Quick Disconnects

August 11, 2020 by Beswick

Quick disconnect fittings (abbreviated as “QDCs” or “QDs”) are used to provide fast and easy connection and disconnection of fluid lines.

Whitepaper Overview 

Quick disconnect fittings (also known as QDCs or QDs) are used to provide fast and easy connection and disconnection of fluid lines. These fittings are also known as quick connects or quick release couplings, which are typically operated by hand. There is a myriad of quick disconnect fittings across all types of industries that are often are used to replace fitting connections that require tools to assemble and disassemble. 

Engineers can use quick disconnects to enhance the serviceability of their design and add value to their product. The ease and speed of connections and disconnections will also save valuable time during testing and development.

To ensure success, many design considerations must be taken into account before specifying a quick disconnect. Since these fittings have a number of components in the waterway (fluid path), they often have a higher pressure drop than simpler fittings. Designers should confirm that the fitting can deliver the flow performance required by their design. Quick disconnects can also have pressure limitations, so it is crucial to ensure the specified fitting can handle the maximum service pressures of the application. 

In this whitepaper from Beswick, learn more about the basics of quick disconnects and how they can improve the end user’s experience by simplifying connections/disconnections and preventing fluid leakage.
