The M3 nozzle (IWS-7044 / I7044) is the original 0.3mm fluid nozzle for the Iwata Revolution M1 — a gravity-feed, single-action airbrush designed for precise, straightforward spraying.

Together with the matching 0.3mm needle, this nozzle forms part of the M1's R3 head system. The 0.3mm bore delivers a versatile range — from very fine lines up to approximately 25mm (1") wide patterns — with clean atomisation at low pressures (20–30 PSI). This makes it well suited to hobbyists working with smaller compressors.

When a nozzle becomes worn, cracked, or deformed (often by a previously bent needle pressing against the bore wall), even a brand-new needle can't deliver a clean pattern. Replacing the nozzle restores the precise bore geometry your M1 was built around.

Iwata's own M Series manual recommends keeping a spare nozzle on hand for unforeseen accidents — they're small, delicate, and the most common casualty of routine maintenance mishaps.

1 × Iwata 0.3mm Fluid Nozzle M3 (IWS-7044) in original Iwata packaging.

✔ Direct fit: Iwata Revolution M1 (HP-M1, gravity-feed, single-action)

✘ Does NOT fit: Revolution M2 (0.4mm), Revolution HP-CR, HP-BR, Eclipse, Neo, Hi-Line, Custom Micron, or any other Iwata series

🔗 Pairs with: 0.3mm needle for Revolution M1 — for best results, replace both the nozzle and needle together. A worn nozzle can be deformed by a previously bent needle, and vice versa.

🔸 Keep a spare. Iwata's own M Series manual recommends having a replacement nozzle ready for unforeseen accidents — it's the part most likely to be damaged during cleaning or maintenance.

🔸 Use a proper nozzle wrench. Never use pliers or the basic spanner from the airbrush kit. A dedicated Iwata nozzle wrench reduces the risk of cracking or cross-threading.

🔸 Don't overtighten. The nozzle only needs to be snug — finger-tight with a quarter-turn from the wrench. Over-tightening is the most common cause of cracked nozzles.

🔸 Replace needle and nozzle together. If your old needle was bent, it likely deformed the nozzle bore. A new nozzle with the old bent needle won't restore a clean pattern.

🔸 Don't remove the nozzle unless necessary. Routine cleaning rarely requires it. Only take the nozzle out if it's visibly damaged, irreversibly clogged, or you're replacing it.

▸ This nozzle fits the Revolution M1 only. It does not fit the M2 (0.4mm) or any other Iwata model — double-check your airbrush before ordering.

▸ A new nozzle alone won't fix problems caused by a bent needle, worn needle packing, or clogged paint channels — those issues need addressing separately.

▸ 0.3mm is a detail-oriented size. For heavy primers and fast coverage on large surfaces, a larger nozzle (0.4–0.5mm) in a different airbrush will be more practical.

▸ Nozzle replacement carries a risk of thread damage if done carelessly. Use the right tool, don't force it, and if you're not confident — consider professional fitting.

🔹 Replacing a cracked, worn, or deformed nozzle on your Revolution M1

🔹 Restoring factory spray performance after needle damage (replace both together)

🔹 Miniature painting, scale modelling, body art, and fine detail work

🔹 Keeping a spare on hand — Iwata recommends it, and for good reason
