Bambu Lab PTFE Tube - AMS Hub

Bambu Lab PTFE tube for AMS Hub filament routing, part FAT003-R. PTFE tubing guides filament between components while reducing feeding resistance.

Choose the correct tube route

Bambu Lab specifies a 4 mm outer diameter and 2.5 mm inner diameter for its PTFE tubing. The required length depends on the printer, connection points and placement of the AMS. Match your setup using the official PTFE tube specifications and connection guide before installation.

This listing is for the tubing. An AMS Hub or other connection hardware is selected separately.

Installation and maintenance

Measure the required route and, where cutting is needed, make a straight cut perpendicular to the tube. Inspect the tubing regularly for wear, particularly when using abrasive filament, and replace visibly worn sections to help prevent feeding problems.
