Elegoo Silicone Sock For Neptune 4/ 4 Pro

Elegoo Silicone Sock For Neptune 4/ 4 Pro is the heat-resistant silicone cover for the hotend heating block on the ELEGOO Neptune 4 and Neptune 4 Pro. It wraps the block to keep heat even around the nozzle and to cut down on plastic build-up.

What it does

Air from the part-cooling fan can pull heat away from the block; the sock shields it, so nozzle temperature stays steadier. When filament oozes or blobs, it sticks to the sock instead of the metal block, which is far easier to clean.

When to replace it

• The sock is torn, stretched loose or turning brittle
• Burnt plastic is baked on and will not peel off
• The old sock was damaged while changing the heater, thermistor or heating block

How to replace it

Switch off and let the print head cool fully. Remove the print head cover and fan bracket as in the ELEGOO Wiki guide, pull off the old sock, fit the new one snugly around the block and reassemble.

This part is for the Neptune 4 and 4 Pro; the Neptune 4 Plus / 4 Max use a different print head. Check your model before ordering, or ask our team by chat.
