This disconnect is handy for my second airbrush there is a rubber seal inside of the threaded end that creates the seal to the airbrush.
Always great service when I have shopped here. Items arrive quickly and I use Iwata and they have a great supply of parts.I love Iwata airbrushes. Easy to use easy to clean. And the parts are available and affordable.
I love these devices. They make removing the airbrush from the hose so much easier and faster.
