Worked perfectly. I, unfortunately, over tightened the previous 0.3 MM nozzle, shearing the threaded portion. That 0.3 MM is the mainstay of my airbrushing. Wished I could have purchased only the nozzle, but it is what it is.
Note: from reading forums on making less expensive air brushes work better, they said polish the needle well before using and paint flows much better. I used the "as received" needle and it sprayed fine. I then polished it, and was not noticeably better, so I thank you for making the product great right out of the box.
