Airbrush needle and nozzle size guide
Millimetre sizes appear here only when a manufacturer or brand-store page we opened published them. Iwata’s U.S. official sheets for NEO CN and Eclipse HP-CS name head systems (N3, E3) and do not list a nozzle diameter in millimetres, so we do not invent one.
Sizes we could verify
| Source listing | Published size or head | What that listing says it is for |
|---|---|---|
| Master Airbrush G233 Pro Set (TCP Global) | Three setups: 0.2 mm, 0.3 mm, and 0.5 mm needles, fluid tips, and air caps | The 0.2, 0.3, and 0.5 mm “fluid tip set-ups allow this extremely versatile airbrush to be used for extra fine detail spray, overall spray or for 2" wide background spray.” |
| NEO for Iwata CN (official U.S. page) | Head system “N3 - Needle, Needle Cap, Nozzle, Nozzle Cap”; nozzle type “Screw-On.” No millimetre figure on that page. | “Fine to wide” spray scale; optimal working pressure 8–20 psi; 7 ml and 3 ml cups. |
| Iwata Eclipse HP-CS (official U.S. page) | Head system “E3 - Needle, Nozzle, Nozzle Cap”; nozzle type “Compression Fit.” No millimetre figure on that page. | “Fine to wide” spray scale; high flow that “allows it to atomize a wider variety of liquids with less need for reducing or thinning”; optimal working pressure 25–35 psi. |
| Paasche H Single Action listings (H-1AS and related) | Head sizes referred to as #1 / #3 / #5 in the H family, not millimetres, on the listings we opened. H-1AS comes assembled with a size #3 head. | H-1AS: fine lines as narrow as 1/16 in and patterns up to 1-1/2 in wide. |
Claims we left out on purpose
- Iwata millimetre conversions. Dealer pages and foreign-market SKUs sometimes print 0.30 mm or 0.35 mm for Eclipse-family brushes. We did not treat those as a substitute for the U.S. official HP-CS or NEO CN sheets, which do not state a mm size.
- Master Airbrush G22. The official TCP Global product title says “0.2mm Tip” and the body text says “0.3mm needle & nozzle.” Until the brand reconciles that listing, we do not quote a G22 size.
- A universal “best size for Gunpla.” That would be our opinion, not a manufacturer specification. The only brand that published a three-size job split on a page we opened is Master Airbrush, on the G233 set: 0.2 mm for extra-fine detail, with 0.3 mm and 0.5 mm in the same kit for overall and wider background work as quoted above.
Head-system parts (needles, nozzles, caps) should be bought as the matching set the maker names — N3 with N3, E3 with E3 — because that is how the official tables group them. Return to the beginner airbrush guide.
