Features of the pneumatic quick coupling

Technical specification

Applications of the 3/8" quick coupling

• Connecting pneumatic tools (impact wrenches, grinders, hammers, screwdrivers)
• Installing compressed air supply hoses in vehicle workshops
• Pneumatic systems in manufacturing plants and assembly lines
• Connecting spray guns, blow guns and inflation guns
• Compressed air installations at vehicle service stations
• Connecting airbrushes in model-making and painting workshops
• Pneumatic systems in agricultural and garden machinery
• Temporary pneumatic installations on building sites and work sites

Use and maintenance

Before first use, check that the thread is clean and remove any contamination. The female thread is screwed onto a component with a 3/8" male thread – a hose, tool or manifold. Tighten the connection by hand first, then with an open-ended spanner, avoiding excessive force that could damage the thread.

To connect to the socket, push the plug in until you hear a click. Before starting the system, it is worth checking for leaks by listening for any escaping air. To disconnect, press the release ring on the socket and pull the plug out.

During use, periodically check the condition of the seals and the locking mechanism. Worn seals can cause leaks, which lowers the working pressure and increases compressor consumption. If connecting or disconnecting becomes difficult, clean the components of dust and oil contamination. Do not use excessive force when connecting – if the plug does not slide in smoothly, this may indicate incompatible profiles or a contaminated mechanism.
