Tamiya 10325 Needle: The Replacement for HG 74532 and 74537
Choose the Tamiya 10325 HG Airbrush Needle when replacing the needle in a 74532 HG III or 74537 HG with integrated cup. Those are the two airbrushes on Tamiya's compatibility list. The part number is especially useful when a listing shortens an airbrush's name to simply “HG.”
Match the needle before opening the case
A needle's appearance does not reliably identify the airbrush it belongs to. Find your model number on the equipment's documentation or packaging and compare it with the supported pair. Do this before removing the replacement's protective pieces or mixing it with other spares.
| Airbrush pair | Listed needle | Listed 0.3 mm nozzle |
|---|---|---|
| 74532 and 74537 | 10325 | 10327 |
| 74510 and 74540 | 10326 | 10327 |
The table shows why sharing a nozzle does not make the needles interchangeable. If your airbrush is not listed, look for its specified service part rather than adapting a needle from the nearest-looking HG model.
A replacement decision, not a diagnosis
Check the needle's condition using the airbrush's inspection guidance. Poor paint flow can involve cleaning, paint preparation or another component, so an uneven test spray alone does not tell you to buy a needle. If inspection identifies a damaged needle in a listed model, the 10325 is the relevant replacement to consider.
The supplied protective tip cover and clear case are useful for keeping the fine point away from other tools. Store a spare in its case rather than loose in a drawer. During fitting, follow the instructions for your exact 74532 or 74537 and stop if a part does not seat as described; additional force does not establish compatibility.
Keep the two service parts distinct
The long needle and the small front nozzle are separate items. Tamiya lists the 10327 nozzle for both supported airbrushes. Inspect it separately when the manual calls for that check, and order it only if your maintenance task needs it.
Frequently asked questions
Will 10325 fit an HG trigger airbrush?
The 10325 list is 74532/74537. For the 74510 and 74540 trigger models, Tamiya lists 10326 instead.
Does 10325 fit every 0.3 mm airbrush?
No universal fit is stated. Nozzle diameter alone does not confirm needle geometry or how it seats in another airbrush.
What comes with the needle?
Tamiya includes a protective tip cover and clear plastic case. A complete airbrush, nozzle and cleaning tools are separate products.
