Air clog

[Quarinteen]

One of my brushes is getting restricted air flow for some reason. I have taken it all the way apart and cleaned it I connect a different brush it works fine.

This one brus though doesn't matter what psi I put it at it blows the same amount of air. Sometimes it will work right for a second then back to low pressure.

It's one of the master air brushes. Not sure the model number but they all seem to be the same. It's gravity fed

Sound more like you soak the entire airbrush and the air valve seal is swollen to tight to allow air to flow right.
Or that seal has gotten damaged not allowing it to flow.

Yup I'd say something is wrong with the valve seal.

You cant submerge the air valve on a master. I did this and got the same results. Ordered new seals from tcp global and everything back to normal.

One of my brushes was doing this but nowI cant remember how I fixed it
