If you own a ribbon-cable Neptune 4 or 4 Pro, those kits are not listed for it. Confirm your version before you order.

What ELEGOO lists
ELEGOO lists its hardened steel nozzle kit as compatible with both the ribbon-cable and Type-C versions of the Neptune 4 Plus and 4 Max.[1] For the Neptune 4 and 4 Pro, the same page says the kit is compatible with the Type-C version only.[1] ELEGOO's multi-size brass nozzle kit carries the same rule.[2]
| Printer | Ribbon-cable version | Type-C version |
|---|---|---|
| Neptune 4 | Not listed | Listed |
| Neptune 4 Pro | Not listed | Listed |
| Neptune 4 Plus | Listed | Listed |
| Neptune 4 Max | Listed | Listed |
This applies to these two nozzle kits only. Do not stretch it to extruders, cables, plates or other parts: check each part's own page.
Identify your version before ordering
Both kit pages carry a notice to verify your version before purchase. The version names describe how the print head is connected: by a ribbon cable or by a Type-C cable. If you cannot tell which you have, ask ELEGOO support with your printer's details before you buy. Our guide to identifying your printer and its revision covers where model and revision information usually sits.
Third-party "Neptune 4" nozzles show the same risk. A seller's listing that says "fits Neptune 4" may not say which version; treat that as the seller's sizing, not a confirmed fit.
The Neptune 4 Pro as ELEGOO lists it
- Build volume: 225 x 225 x 265 mm.[3]
- Firmware and extruder: Klipper pre-installed, with a dual-gear direct extruder.[3]
- Nozzle temperature: 300 °C maximum on ELEGOO's global page.[3] The same page lists a 100 °C bed maximum; a US listing may give a different bed figure, so check the page for your region.
- Input: 115/230 V, 50/60 Hz.[3] The page does not say whether a switch selects the voltage. Read your unit's label and manual; see printer power supplies and voltage.
The Neptune 4 Plus as ELEGOO lists it
- Build volume: 320 x 320 x 385 mm, with a 330 x 330 mm PEI printing platform.[4] Order a replacement sheet by the platform size.
- Firmware and extruder: Klipper, with a dual-gear direct extruder at a 5.2:1 reduction ratio.[4]
What we could not confirm
We could not read the Neptune 4 Plus user manual, so we cannot confirm its bed-tramming method or its electrical ratings from the manual. Use the manual that came with your printer for both.
Where ELEGOO says to buy
ELEGOO's authorized-reseller page tells buyers to purchase from ELEGOO official stores or listed resellers, and for the US and Canada it points to its own us.elegoo.com and ca.elegoo.com stores.[5] It does not name an Amazon or AliExpress store, so a marketplace seller's "official" label is not confirmed by ELEGOO.
