Bambu P2S Nozzle Change: Safe Quick-Swap Guide
The Bambu P2S uses a clip-retained quick-swap hotend, not a threaded nozzle. Power off, remove the sock, release the clip, seat the replacement fully, refit the sock and update the nozzle setting.
The Bambu P2S uses a clip-retained quick-swap hotend. The supported replacement procedure does not use a nozzle wrench, threaded brass nozzle or hot-tightening step.
Bambu's current range lists 0.4, 0.6 and 0.8 mm hardened-steel hotends and a 0.2 mm stainless-steel hotend for the P2S. Choose a complete hotend that is explicitly compatible with the P2S.
When to change the hotend
Bambu lists three main reasons for replacement:
- a clogged hotend;
- a damaged hotend; or
- a change of nozzle specification.
A different diameter needs matching settings in the printer and slicer. A material change should be driven by filament compatibility, especially when abrasive filler is involved.
What you need
- A compatible P2S hotend in the required material and diameter
- Thermal-insulation gloves

Safe P2S hotend replacement
1. Power off and disconnect
Bambu says to power off and disconnect the printer before maintenance. Let the hotend cool and do not touch the lower heat block with bare skin.
2. Open the toolhead cover
Open the magnetic front cover and hang it on the toolhead as shown in Bambu's guide.
3. Remove the silicone sock
Hold both sides of the silicone sock and pull it diagonally downwards to remove it.
4. Release the hotend clip
Unlock the right-hand side of the clip first, then release the metal plate on the left. Hold the upper and lower ends of the heatsink and remove the hotend.
If filament residue prevents easy removal, stop and follow the specific residue note in Bambu's illustrated guide. Do not force the hotend or damage the nearby wiring.
5. Install and secure the replacement
Open the clip fully and fit the new hotend onto the heating assembly. Confirm full contact, close the left metal plate, then press the right-hand ring into place.
Refit the silicone sock from bottom to top. It should sit straight and fully against the hotend. Close the magnetic front cover.
6. Update the nozzle setting
If the diameter or material changed, update it on the P2S screen under Filament > Nozzle & Extruder > Nozzle Type before printing. Confirm that the hotend is secure and the silicone sock is not tilted.
Choosing a diameter
0.2 mm stainless steel is the fine-detail option in Bambu's current P2S range.
0.4 mm hardened steel is the general-purpose size.
0.6 mm and 0.8 mm hardened steel provide wider extrusion paths for larger parts and higher flow, with less fine detail.
Use the filament compatibility table on Bambu's official hotend product page rather than assuming every filament works with every diameter.
