Pneumatic Quick Connect Couplings

Pneumatic technology uses pressured gas to drive some sort of mechanical motion. The most common gas used in pneumatic technology is dry air. The air must be dry as moisture has different compressive qualities. Pneumatic technology is very similar to hydraulic technology, however the fluid used to drive the motion here is always a liquid.

Pneumatic systems are operated using a central pneumatic device (such as an air motor or compressor) and utilise manual or automatic solenoid valves to control the airflow around the system.

Pneumatic systems contain many components, pneumatic quick connect couplings being one example.

What are pneumatic quick connect couplings used for?

Pneumatic quick connect couplings attach onto the end of hoses and allow them to connect quickly and easily to different types of equipment. These are often seen in locations where tools will be changed frequently, such as in dental surgeries.

Types of pneumatic quick connect couplings

Pneumatic quick connect couplings come in a variety of sizes, seals, connections, thread sizes, grades and materials. These adaptors allow the user to change the hose in a system so an assortment of tools can be interchanged quickly.
