Elegoo Heating Block For Neptune 4/ 4 Pro

Elegoo Heating Block For Neptune 4/ 4 Pro is the hotend heating block for the ELEGOO Neptune 4 and Neptune 4 Pro. This square metal block holds the heater cartridge, the thermistor and the nozzle together, and carries heat into the filament before it is extruded.

When to replace it

• The nozzle thread is damaged, the nozzle will not tighten, or filament leaks around it
• Burnt plastic has built up and will not clean off
• The block is deformed or damaged after a filament blob

Before you buy

The product name covers the heating block only. If you also need a heater, thermistor, nozzle or silicone sock, ask our team by chat before ordering.

Fitting it

Work with the printer off and the hotend fully cool. Insert the heater so both ends sit flush with the block, tighten its screw with a 1.5 mm hex key and the thermistor screw with a 2.0 mm key, as in the ELEGOO Wiki guide. Refit the silicone sock, test heating and re-level the bed.

Fits the Neptune 4 and Neptune 4 Pro (the Neptune 4 Plus / 4 Max use a different heater). Check your model before ordering.
