Replacement 4-in-1 feeding pipe for the AMS unit of Bambu Lab X1, X1C, P1S and P1P printers. An alternative clone of the original part that serves as a junction merging four PTFE tubes from the AMS into one main tube leading to the extruder. An ideal replacement for a worn or damaged original - without any compromise in functionality.

A key part for reliable filament feeding

The 4-in-1 transmitter, or PTFE tube merger, is a key component of the AMS system. It ensures smooth filament routing from the four AMS slots into a single output that continues to the print head. Without this part, automatic material switching cannot operate - which is why it is always wise to keep a spare on hand.

An alternative to the original at a reasonable price

The clone is made from quality materials and matches the dimensions of the original Bambu Lab part exactly. Installation is the same as with the original - simply disconnect the old PTFE tubes, swap the merger, and click them back in. You save money without losing any functionality.

Compatibility with the P1 and X1 series

The part is designed for Bambu Lab X1, X1 Carbon, P1S and P1P printers in combination with the AMS unit. If you use any of these models and want to have a backup against downtime on hand, this replacement is a good choice.

Simple replacement in just a few minutes

The merger uses standard pneumatic quick couplers for 4 mm diameter PTFE tubes. Replacement requires no special tools - just press the coupler ring and pull out the tube. When reassembling, make sure the tubes are pushed in all the way.

A key link in the AMS system

AMS (Automatic Material System) enables printing with up to four materials at once and unattended filament switching. For the system to work flawlessly, it needs high-quality feeding paths - and the 4-in-1 pipe is exactly the point where four paths merge into one. Any leaks or wear will show up as feeding issues, so it pays to check its condition and keep a spare in reserve.

Suitable for a wide range of filaments

The merger is designed for standard 1.75 mm filaments - PLA, PETG, ABS, ASA, nylon and polycarbonate. For flexible materials such as TPU, however, it is better to print outside the AMS, as soft filament easily jams in the feeding system.
