Bambu Lab Nozzle Wiping Pad — H2S

Bambu Lab Nozzle Wiping Pad — H2S

Every print on your H2S starts with a clean nozzle. The purge wiper drags the hotend across a soft silicone wiping strip to scrape off residual filament left behind after purging and filament changes — and because that strip does its job on every single print, it is a consumable. This is the genuine Bambu Lab replacement kit for the H2S, with enough strips to cover a long stretch of printing plus the screws and silicone block needed to fit them.

Swap the strip the moment it looks aged, cracked or torn. A degraded wiper smears molten plastic back onto the nozzle instead of removing it, which shows up as blobs on the first layer, stringy seams and dark specks dragged into light-coloured prints.

Key features

• Made for the H2S wiping system. The wiping strip mounts to the purge wiper inside the left-hand lining of the printer, where the nozzle is wiped clean after waste material is purged.
• Soft silicone wiping surface. Bambu Lab specifies a soft silicone contact face so the strip conforms to the hotend during the wipe rather than skipping over baked-on residue.
• Hands-off operation. Cleaning runs automatically as part of the print-start routine — you don't add a step to your workflow, you just keep the consumable fresh.
• Simple, screw-fixed replacement. Power the printer off, remove the worn strip and secure the new one to the purge wiper with one of the supplied BT3-8 screws. Bambu Lab publishes illustrated H2S guides for both the wiping assembly and the wiper strip.
• Spares on hand. Three strips and three screws per kit means a worn wiper never becomes a reason to pause a job — handy for schools and small production shops running the H2S daily.

Who it's for

Any H2S owner doing routine maintenance — whether that's a hobbyist who has noticed first-layer blobs creeping in, a maker running multi-colour jobs that purge constantly, or a school or small business that wants a spares drawer so a worn wiper never stops a class or an order. If you print in several materials and colours, the wiper works harder and wears faster, so keeping a kit on the shelf is cheap insurance.

What's in the box

• 3 × Nozzle Wiping Strip
• 3 × BT3-8 Screw
• 1 × Nozzle Wiping Silicone Block

Please note: this is the H2S kit. The H2D, H2D Pro and H2C use a different clip-in wiping pad (part FAW005) that is sold separately — the two are not interchangeable, so check your model before ordering.

Specifications

Fitting tips

• Power the printer off at the wall before reaching into the enclosure.
• Work with the hotend cold — the wiper sits directly in the nozzle's path.
• Keep the spare screws with the kit; the BT3-8 screw is specific to this assembly.
• While you're in there, check the purge wiper itself and the waste chute for packed filament — a clogged chute will foul a brand-new strip quickly.
• Follow Bambu Lab's official H2S wiki guides ("Nozzle Wiping Replacement" and "Nozzle Wiper Strip Replacement") for the illustrated step-by-step.
