This is an Iwata .3mm Fluid Nozzle, intended for use with the HP-BC airbrush.
Each nozzle is precisely made on the industry’s most sophisticated machinery. They are hand tested to assure accurate control and fine atomization of the spray, and they are self-sealing, which eliminates the need for messy sealers. Unlike conventional brass nozzles, steel alloys are more durable and resist damage from harsh chemicals.
Fits C, BC.
