The Bambu Lab PTFE Tube Coupler is the OEM replacement push-fit fitting for securing PTFE tubes at key connection points along the filament path in Bambu Lab printers. The coupler provides a quick-connect, quick-release mechanism that holds the PTFE tube firmly under filament load while allowing it to be removed easily by pressing the collar ring. Correct coupler function is critical for maintaining a gap-free filament path between tube sections.

Worn couplers lose their grip force, allowing the PTFE tube to pull out slightly under retraction loads, which creates a small gap that filament can melt into and jam. This OEM coupler restores the original push-fit retention force and provides a clean seat for the PTFE tube at hotend and bowden path junctions, eliminating a common root cause of jams and under-extrusion.

Key features

• OEM push-fit PTFE tube coupler for hotend and bowden path connections in Bambu Lab printers.
• Holds the PTFE tube firmly under filament load and retraction forces to prevent gap formation.
• Quick-release collar ring for easy PTFE tube changes without tools.
• Restores original grip retention when the existing coupler has loosened or cracked.
• Eliminates jams and under-extrusion caused by PTFE tube pull-out at the coupler junction.

Compatible with: Bambu Lab P1P, P1S, X1, X1C, X1E
