The N5 nozzle (IWN-0804 / N0804) is the original 0.5mm fluid nozzle for the Neo for Iwata TRN2 — a side-feed, pistol-trigger airbrush built for high-flow, general-purpose spraying.

Together with the N5 needle (IWN-0754), this nozzle forms the core of the TRN2's spray system. The 0.5mm bore is designed for high paint flow — primers, varnishes, basecoats, and heavier paints all move through comfortably, with spray patterns reaching up to approximately 38mm (1.5") at optimal settings. Experienced modellers describe this combination as a genuine all-rounder for coverage work.

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 TRN2 was designed around.

This nozzle does not include an o-ring. If your nozzle seal also needs replacing, source the appropriate o-ring separately.

1 × Iwata N5 Fluid Nozzle 0.5mm (IWN-0804) in original Iwata packaging. O-ring not included.

✔ Direct fit: Neo for Iwata TRN2 (side-feed, pistol-trigger airbrush)

🔄 Conversion fit: Neo for Iwata TRN1 (gravity-feed) — requires additional N5 needle (IWN-0754), N5 head base, and N5 nozzle cap

✘ Does NOT fit: Neo CN, Neo BCN, Eclipse, Revolution, Hi-Line, Custom Micron, or any other Iwata series

🔗 Pairs with: N5 Needle 0.5mm (IWN-0754) — for best results, replace both the nozzle and needle together. A worn nozzle can be deformed by a previously bent needle, and vice versa.

🔸 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 into an oval shape. A new nozzle with the old bent needle won't give you a clean pattern.

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

🔸 Never push anything into the nozzle from the front. No pins, no wire, no brushes forced through the bore. Clean from the back only — or soak the entire head assembly in airbrush cleaner.

▸ This nozzle is designed for the Neo TRN2. It does not drop into the Neo CN, Neo BCN, or other Iwata series — double-check your airbrush model before ordering.

▸ O-ring is not included. If your existing nozzle seal is worn or damaged, you'll need to source a replacement o-ring separately.

▸ At 0.5mm, this nozzle is built for coverage — primers, basecoats, varnishes. For very fine lines and minimal overspray, a 0.35mm (N3) setup will give you more control.

▸ 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.

▸ 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 Neo TRN2

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

🔹 Converting a Neo TRN1 from 0.35mm to a broader 0.5mm coverage setup

🔹 Keeping a spare on hand — nozzles are fragile and easily damaged during maintenance
