Airbrush Quick Couplings

What Are Airbrush Quick Couplings and What Are They For?

Quick couplings are incredibly practical accessories in any modeler's airbrushing arsenal. Their main function is to allow for the instant connection and disconnection of the airbrush from the air hose, without the need to screw and unscrew fittings each time. This simple, two-part device consists of a socket (female part) mounted on the end of the hose and a plug (male part) screwed into the airbrush. The connection is made by simply pushing the plug into the socket, accompanied by a characteristic 'click', while disconnection only requires pulling back the socket's sleeve. This solution not only significantly saves time, especially when working with multiple airbrushes, but also protects the delicate threads on both the tool and the hose from wear and damage.

How to Choose an Airbrush Quick Coupling?

The primary selection criterion is the thread size. The most common standard in airbrushing is the 1/8 inch thread, and most quick couplings on the market are compatible with it. However, it's always wise to confirm the thread size of your airbrush and hose. There are various types of quick couplings available. The simplest models only serve the purpose of connecting. More advanced versions, such as quick couplings with a built-in pressure adjustment valve (also known as a MAC valve), allow for precise control of airflow directly at the airbrush, which offers great convenience. Sets are also available that include one socket and several plugs, which is an ideal solution for users who own multiple airbrushes for different applications.
