What Is This?
OEM 0.5mm replacement needle, part number 40461, for GHAD-39 and GHAD-68. The everyday workhorse size — primers, base coats, clear coats, terrain. Multiple polishing stages produce consistent, clean paint release. Note: separate SKU from the unlabelled 0.5mm needle also listed.
Where 0.5mm Sits
| Size | Best For |
| 0.35mm | Panel lines, pre-shading, miniatures |
| 0.5mm ← you are here | Primers, base coats, clear coats, terrain |
| 0.7mm+ | Large area, automotive |
When to Replace
⚠️ Tip blunt — spatter or uneven spray after correct pressure
⚠️ Bent needle — asymmetric pattern
⚠️ Surface scratches — intermittent flow
🔄 Every 50–100h, or always when replacing nozzle
⚠️ Heads Up
Advanced Series only — does not fit Ace (GHAC) or Premium (GHPM) models.
Replace needle and nozzle as a matched pair — 0.5mm needle requires 0.5mm nozzle.
