This connector is screwed into the end of your Badger air hose and by simply sliding the spring loaded sleeve back, the airbrush is disconnected. Note that this item is self sealing when disconnected, preventing the need to remove air pressure from the hose before changing air tools.

Please note that you will also need a suitable tail to connect to your airbrush to the Quick Release Coupling Body. 

This quick release airbrush body will fit any Badger air hose.
