If you want to convert your spray gun to the Medium nozzle size, please replace the air nozzle, needle (Item No. 37213) and the paint nozzle (Item No. 37053) together.
We recommend our complete conversion kit (needle and paint nozzle art. no. 37083) for conversion. This spare part is only suitable for the Spray Gun Standard Class (Art.-No. 39101, resp. Art.-No. 39201).
