Elegoo Silicone Sock For Neptune 4 Max

Elegoo Silicone Sock For Neptune 4 Max is the black silicone cover that wraps the hotend heating block on the ELEGOO Neptune 4 Max. It keeps the hotend temperature steady and stops oozing filament from sticking to the block.

Why it matters

• Reduces heat loss from the part-cooling fan, so nozzle temperature stays more stable
• Keeps molten plastic off the block, so burnt residue does not build up
• Covers the heating block and the ceramic heating element on its back

When to replace it

• The sock is torn, hardened or loose on the block
• Burnt plastic is stuck to it and will not come off
• After a large filament blob around the nozzle

How to replace it

Only remove or fit the sock when the nozzle is completely cool. On the Neptune 4 Max you first take off the print head front cover and fan bracket, then pull off the old sock and push the new one snugly over the block.

ELEGOO's guides treat the Neptune 4 Plus and 4 Max print heads together. If you own a 4 Plus or are unsure, ask our team by chat before ordering.
