📐 0.35mm🏷️ Part 40454✅ GHAD-39 · GHAD-68✨ Multi-Polish
✅ GHAD-39 · GHAD-68 (Advanced Series) only — does not fit Ace or Premium Series
What Is This?
OEM 0.35mm replacement needle — the stock size on the GHAD-39. Narrow enough for panel lines, pre-shading, and miniature work; enough flow for blending and small base coat passes. Multiple polishing stages produce an extremely smooth taper for clean, consistent paint release.

Notes · Q & A
Will this spare part fit my airbrush?+
Check the exact model name against the Compatible with row on the product page. Parts from the same maker are not automatically interchangeable, even when they look similar or fit different assemblies on one model.
How do I work out which replacement part I need?+
Air or paint leakage can involve more than one sealing component, so the symptom alone does not identify the exact spare. Compare the part name and Format row, then match the Compatible with entry to the model printed on your airbrush.
Are these genuine manufacturer parts?+
Yes. The Gaahleri listings contain the maker’s own parts supplied through its channel, while the Iwata replacements are identified as genuine OEM parts or genuine spares.
How many parts come in the pack?+
Pack quantities vary between listings. Check the Pieces row for the confirmed count; where that field is absent, the manufacturer has not published a quantity.
Are measurements available for matching seals or threaded parts?+
The manufacturers do not publish seal diameters, cord thicknesses or thread measurements for these listings. Identify the replacement through its part code, Format and exact Compatible with entry rather than by visual estimation.
