Mystic spray problem
 

My Mystic booth is having a spray problem out of the middle nozzle. It spitting a little and leaks when I look at the back. The meter and check valves are good. It looks like there is some crack on the part.

Is there any one can help me to find a part for that? The mystic tech support don't sell separate part but it cost more than the whole booth worth to replace the whole nozzle, which I don't want to.

I another forum someone suggested www.clippard.com part # sdr 17-5 but I don't see the certain part number on that site. anyone has an idea?
