The Bambu Lab PTFE Coupler is the OEM replacement push-fit fitting used to connect PTFE tubes at the hotend, bowden path junctions, and AMS assembly connection points in Bambu Lab printers. The coupler grips the PTFE tube securely while allowing easy release, ensuring a tight, leak-free connection that maintains reliable filament routing throughout the feed path.

Over time, couplers can become loose, crack, or lose their grip force, causing the PTFE tube to slip or pull out under filament load. Replacing a worn coupler with this OEM part restores a secure connection and eliminates feed path gaps that can cause jams, under-extrusion, or filament grinding. This is a small but critical component for maintaining a reliable filament path.
