Bought this for a GSI Creos airbrush that shares many compatible parts with the Iwata HP-CS.
Replacing the crown lets you use backflow to mix in pot, and this part fits perfectly in place of the crown tip.
I am SO pleased to have gotten this gear so fast and all the parts fit my other guns that needed an upgrade till I can get more new ones. Thank you so much for helping me and the lil maple treats were a great surprise. Thanks Danica
