Elegoo Hotend

Pre-assembled extruder hotend kit - a direct replacement or upgrade for your Elegoo 3D printer. Ready to install out of the box, each kit includes the nozzle, ceramic heater, and thermistor for quick setup and consistent performance.

Select your printer and cable type below, then choose your nozzle material and size. Hardened Steel handles abrasive filaments (carbon-fiber, glow-in-the-dark) with less wear; Brass delivers excellent thermal conductivity for everyday PLA, PETG, and ABS printing.

Neptune 4 owners: one hotend fits every Neptune 4 Plus and 4 Max (flat or Type-C cable) and the Type-C Neptune 4 and 4 Pro.

• Neptune 4 Plus or 4 Max: always choose Neptune 4 Plus/4 Max (any cable), 4/4 Pro Type-C, whatever cable your printer has.
• Neptune 4 or 4 Pro: look at the cable that runs to your print head. A round cable with a Type-C plug: choose Neptune 4 Plus/4 Max (any cable), 4/4 Pro Type-C. A wide flat ribbon cable (older units): choose Neptune 4/4 Pro - Flat Cable.

Centauri Carbon 2 owners: to replace the hotend itself, choose 0.4mm (Full Assembly): the complete Centauri Carbon 2 hotend, pre-assembled with its 0.4 mm nozzle, heater and thermistor. The 0.4, 0.6 and 0.8mm options are Elegoo's quick-swap units, a brass body with a hardened steel tip (the size is engraved on the tip). The ceramic heater and thermistor stay on your printer, so changing nozzle size takes seconds. Elegoo lists them for the Centauri Carbon, Centauri Carbon 2 and Centauri 2 series.
