Bambu Lab Silicone Sock for P2S, Pack of 3

A hotend sock does its job quietly, right up until it does not. Print enough hours and the silicone around the heater block hardens, cracks, or picks up a crust of scorched filament that no amount of scraping fully removes. From that point the block loses heat faster than it should, the nozzle works harder to hold temperature, and layer adhesion on anything printed above 250°C starts to drift for reasons that are not obvious from the slicer.

This is a pack of three genuine Bambu Lab silicone socks sized for the P2S hotend, so a worn or damaged sock is a two-minute swap rather than a print job you have to abandon halfway through.

Genuine Bambu Lab OEM | Pack of 3 | High-Temperature Silicone | -10°C to 300°C Rated | Toolless Press-Fit | Fits P2S and X2D | Reduces Heat Loss and Filament Build-Up

Who the Bambu Lab Silicone Sock for P2S is built for

Print farm operators keeping machines uptime-ready

Running several P2S units means a cracked sock on one machine should not take that printer out of rotation while you wait on a single spare. A pack of three lets you keep a working stock on hand, swap a damaged sock between jobs, and get a machine back into the print queue in minutes rather than losing it for a day.

Makers doing routine hotend maintenance

If your last few prints have come out with rougher first layers or a faint burnt smell near the toolhead, a scorched sock is usually the first thing worth checking. Replacing it is standard servicing, the same way you would replace a nozzle or a build plate, and having three on hand means you are not waiting on a single replacement to arrive before you can print again.

Engineers printing high-temperature filaments

ABS, PC and other engineering filaments need the hotend to hold a consistent temperature well above 250°C for the full print. A sock that has lost its grip or developed a crack lets heat escape unevenly, which shows up as inconsistent extrusion on exactly the parts where dimensional accuracy matters most.

What sets the Bambu Lab Silicone Sock for P2S apart

A worn sock costs you more heat than it looks like

The sock's job is thermal insulation, wrapping the heater block so the hotend does not bleed warmth into the surrounding airflow, especially with the part cooling fan running nearby. Once the material hardens or splits, that insulation stops working properly, and the hotend has to draw more power just to hold its target temperature, which is exactly when you start seeing under-extrusion on fine detail.

Genuine fit, not a generic wrap

This is the same part Bambu Lab fits to a new P2S hotend, not a universal sock stretched to fit. It seats fully over the heater block with no gaps at the edges, which matters because a loose or ill-fitting sock lets cool air reach the block exactly where it should not.

Toolless press-fit, swapped in under a minute

No screws, no disassembly beyond what routine hotend maintenance already needs. With the printer powered off and the hotend cooled, the old sock pulls away and the new one presses on in one motion, seated firmly at the base of the heater block.

Silicone built for the heat, not just resistant to it

Silicone is the material of choice here because it holds its shape and flexibility across a wide temperature swing, rated from -10°C up to 300°C on this sock, which covers the full working range of the P2S hotend without softening, sagging or picking up a permanent set.

A pack of three, not a single point of failure

Socks are a wear item, not a one-time purchase, so this ships as three rather than one. Keep a spare in the toolbox, get the third one ready for the next filament change, and you are never stuck ordering a replacement mid-project.

Ordering, shipping and support

This sock pack ships by courier nationwide from our Centurion and Boksburg stores, reaching anywhere in South Africa on the same delivery network as the rest of our Bambu Lab range. As a genuine Bambu Lab part, it is covered by the standard accessory warranty, with any claim handled locally rather than through an overseas supplier. If you print in ABS, PC or other engineering filaments regularly, our Bambu Lab P2S spares range and wider 3D printer spare parts collection carry replacement nozzles and hotend components alongside it.

Frequently asked questions

Does this sock also fit the Bambu Lab X2D?

Yes. The P2S and X2D share the same hotend and heater block design, so this sock fits both printers. It is not, however, a match for the P1S, X1C, A1 or H2 series machines, which use differently sized hotends and need their own specific sock.

Can I use it when printing ABS, PC or other high-temperature filaments?

Yes, that is exactly where it matters most. The sock is rated to 300°C, which covers the full temperature range engineering filaments such as ABS and polycarbonate need from the P2S hotend, and keeping the heater block properly insulated helps the nozzle hold that temperature consistently through a long print.

How do I fit the silicone sock, and do I need tools?

No tools are needed. With the printer powered off and the hotend fully cooled, remove the old sock by gripping it firmly and pulling it away from the heater block, then press the new sock on from the base upward until it sits flush. Never attempt this while the hotend is hot, since the heater block reaches temperatures that will burn skin instantly.

How do I know when a sock needs replacing?

Look for cracking, hardening, or a build-up of scorched filament that will not scrape off, and watch for print quality that drifts even though your settings have not changed. Heavy users printing daily at high temperatures typically get through a sock faster than occasional hobbyist use, which is why this comes as a pack of three rather than one.

Is this covered by local warranty and shipped from stock in South Africa?

Yes. As a genuine Bambu Lab part sold through 3D Printing Store, it carries the standard accessory warranty and is handled locally if there is ever a fault. It ships from our own stock in Centurion and Boksburg, so you are not waiting on an international order to keep a P2S running.
