The Bambu Lab PTFE Tube Set for AMS Internal is the official replacement set for the filament routing tubes inside the Automatic Material System unit. This set contains 4x 195mm and 4x 230mm PTFE tubes that guide each filament channel within the AMS, ensuring consistent low-friction transport through all four material slots.

Over time, the internal PTFE tubes of the AMS can wear, develop friction-causing scratches, or deform slightly under heat, leading to filament feed errors or inconsistent switching. This OEM set restores proper filament routing in all four channels and is the correct part for the internal layout of the Bambu Lab AMS unit.
