Tamiya 10327 Nozzle: Which HG Airbrushes Does It Fit?
The Tamiya 10327 HG airbrush nozzle is a 0.3 mm replacement part for four named Tamiya airbrushes: 74510, 74532, 74537 and 74540. Match your airbrush's item number to that list before ordering. A 0.3 mm marking on a different airbrush is not enough to establish fit.
One nozzle, two needle families
The nozzle is the small component at the front of the airbrush. The long needle is a separate part. These four HG airbrushes share the listed nozzle, while Tamiya assigns different replacement needles to the top-button and trigger families.
| Your airbrush | Listed nozzle | Listed replacement needle |
|---|---|---|
| 74532 or 74537 | 10327, 0.3 mm | 10325 HG needle |
| 74510 or 74540 | 10327, 0.3 mm | 10326 trigger-type needle |
This distinction matters when repairing an airbrush with damage to more than one component. Order each replacement against its own compatibility list instead of choosing a matching-looking pair from photographs.
Confirm the problem before replacing a part
Tamiya recommends replacement when the nozzle shows wear or damage. An unsatisfactory spray pattern alone does not identify the cause. Follow your airbrush's cleaning and inspection instructions before deciding which component needs replacement; paint residue, preparation and air delivery also belong in that check.
Work over a clear, well-lit surface and keep the removed parts organized. Use the exact airbrush manual for removal, sealing and tightening. The replacement nozzle listing does not establish a universal torque, sealant choice or disassembly method for other airbrushes. Do not enlarge the opening or force a tool through it to make an uncertain part fit.
What to check before ordering
- Find the airbrush model number on its packaging, paperwork or model identification.
- Confirm that it is one of the four listed models.
- Determine whether you need the nozzle, the needle or both.
- Keep the airbrush manual ready for fitting and the first test after reassembly.
Frequently asked questions
Does this fit the 74545 Super Fine airbrush?
The 74545 is a 0.2 mm model and is not on the 10327 compatibility list. Find the replacement specified for that airbrush.
Will it fit a Sparmax because the nozzle is also 0.3 mm?
Diameter alone does not confirm the thread or shape. The 10327 listing names the four HG models above, so do not substitute it for an unlisted Sparmax nozzle.
Is a needle included with 10327?
This listing is for the nozzle. If a needle also needs replacement, select 10325 or 10326 only where its own fit list matches your airbrush.
