The Bambu 4-in-1 PTFE Adapter is an adapter used to connect the PTFE tube. Compared to the original PTFE tube connector, the 4-in-1 adapter can connect 4 feeder modules to the printer at the same time. (up to 7 different filaments: 1 AMS and other 3 filaments)

It can help users to connect the printer to AMS along with other filaments which are not compatible with AMS such as TPU 95A, Bambu PET-CF and other brands’ carbon-fiber/glass-fiber contained filaments.
