Choose the ten-piece brass kit for extra 0.4 mm replacements and a 1.0 mm option, or compare the five-piece hardened-steel kit when the filament calls for a wear-resistant nozzle.
Fit guide
Check your Neptune 4 toolhead version before ordering
Start by identifying whether your printer is a Neptune 4, 4 Pro, 4 Plus, or 4 Max. Then check the version named in the nozzle listing. On ELEGOO’s multi-size brass kit, the cable revision changes the fit for two of those models.
What to check
- For the official brass or hardened steel multi-size kit, the 4 Plus and 4 Max can use either of the two listed cable versions. ELEGOO limits those kits to the Type-C version of the 4 and 4 Pro.
- Carry that distinction into a shopping comparison. An accessory page that says only “Neptune 4 series” leaves you without the revision detail you need for the 4 or 4 Pro.
- For third-party replacements, compare the actual part number, dimensions, and supported revision. For a complete hotend, also check the connector and assembly contents.

Questions about this choice
My printer is a Neptune 4 Pro with a ribbon cable. Which option should I look for?
Look for a listing that explicitly identifies your Neptune 4 Pro ribbon-cable version. ELEGOO’s two multi-size kits linked here specify Type-C for the 4 Pro.
Can I use the same diameter to compare two kits?
Yes, after you confirm both kits fit your installed toolhead. Compare the opening and material once you have narrowed the choices to the correct version.
