The N3 nozzle (IWN-0803 / N0803) is the original 0.35mm fluid nozzle for the Neo for Iwata TRN1 — a gravity-feed, pistol-trigger airbrush designed for comfortable, detailed spraying with trigger-style control.

Together with the N3 needle (IWN-0753), this nozzle forms the heart of the TRN1's spray system — shaping the paint stream, controlling atomisation, and determining your spray pattern. The 0.35mm bore delivers a versatile range from fine lines (~0.3mm) to medium coverage patterns (~25mm/1"), making the TRN1 a genuine all-rounder for hobby work.

Iwata designed the Neo nozzle system specifically for quality atomisation at low air pressures — a real advantage for hobbyists running smaller compressors. When the nozzle becomes worn, cracked, or deformed (often by a previously bent needle), even a brand-new needle can't deliver a clean pattern. Replacing the nozzle restores the precise bore geometry your TRN1 was built around.

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

1 × Iwata N3 Fluid Nozzle 0.35mm (IWN-0803) in original Iwata packaging. O-ring not included.

✔ Direct fit: Neo for Iwata TRN1 (gravity-feed, pistol-trigger airbrush)

🔄 Conversion fit: Neo for Iwata TRN2 (side-feed) — requires additional N3 needle (IWN-0753), N3 head base, and N3 nozzle cap

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

🔗 Pairs with: N3 Needle 0.35mm (IWN-0753) — 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 one of the most common causes 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 TRN1. 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.

▸ 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 requires care and the right tool. If you're not confident working with small, delicate airbrush parts, consider having it fitted by an experienced user or service centre.

▸ 0.35mm is a versatile all-round size, but for pure coverage tasks (priming large surfaces, heavy primers) a 0.5mm (N5) setup will be faster and less prone to clogging.

🔹 Replacing a cracked, worn, or deformed nozzle on your Neo TRN1

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

🔹 Converting a Neo TRN2 from 0.5mm to a finer 0.35mm detail setup

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