QIDI Max4 hotend silicone cover / silicone sock (5 pcs)

Original silicone sock for the QIDI Max4 hotend extends hotend life, increases temperature stability, and simplifies printer maintenance. The set contains 5 pieces of covers, so you always have a spare part on hand during nozzle replacement or filament dragging accidents.

What the silicone sock is used for

The silicone cover is designed for the QIDI Max4 hotend block (and compatible Q2/Q2C series models):

• Hotend thermal insulation – limits heat loss and helps maintain stable nozzle temperature.
• Protection against filament adhesion – melted plastic is harder to catch on the surface, reducing the risk of burns and debris.
• Better print surface quality – more stable temperature means more consistent extrusion.
• Easy maintenance – simply pull off a dirty or damaged cover and put on a new piece from the set.

Main advantages

• Original part for QIDI Max4 – perfect shape compatibility with the Max4 hotend.
• Heat-resistant silicone – material is designed for long-term use at printing temperatures up to approx. 300 °C.
• Long-term hotend protection – protects the nozzle and block from the cooling air flow and filament deposits.
• Visible hot hotend warning – design with warning graphics (“CAUTION HOT”) helps safer handling.
• Economic 5 pcs pack – ideal as a supply for intensive printer operation.

Compatibility

• Printers: QIDI Max4 (also compatible with the hotend of some QIDI Q2 / Q2C models – always check according to the hotend shape).
• Materials: suitable for both common and technical filaments that Max4 supports (PLA, PETG, ABS, ASA, TPU, PA, PC, and fiber composites) – within the printer's recommended hotend temperatures.

Use and recommendations

1. Let the hotend cool down before removing the old silicone cover.
2. Carefully pull the old cover off the hotend block.
3. Check the cleanliness of the block and nozzle, remove any filament residues.
4. Stretch the new silicone cover over the hotend block so that the hole precisely surrounds the nozzle and the cutout fits in the corresponding places.
5. During the first heating, check that the cover does not interfere with the filament or sensors.

Tip: Always have a spare silicone sock on hand when changing nozzles – in case of mechanical stress or contamination, putting on a new piece is often the fastest solution.

Who the product is suitable for

• Owners of QIDI Max4 who want to keep the hotend in optimal condition.
• Companies, workshops, and operations with intensive printing, where more frequent nozzle changes occur.
• Users printing technical and filled materials, which heat the hotend more and increase the risk of contamination.
