This Sparmax quick release connector is screwed into the end of your 1/8″BSP air hose and by simply sliding the spring loaded sleeve back, the airbrush is disconnected.
This item is self sealing when disconnected, preventing the need to remove air pressure from the hose before changing airbrushes.
The adjustable air control screw allows you to regulate the air pressure from 0-100%.
Please note that you will also need a suitable tail to connect your airbrush to the quick release body.
1/8″ BSP (British Standard Pipe) measures approx 9mm diameter.
