Bambu Flow Blocker — X2D (FAC207)

Official Replacement Flow Blocker • Prevents Inactive Nozzle Oozing • Genuine Bambu Lab Part

Overview

The Bambu Flow Blocker (FAC207) is the official replacement flow blocker for the Bambu Lab X2D. This precision metal component is installed on the toolhead and seals the inactive nozzle during dual-nozzle printing, preventing molten filament from dripping or oozing while the other nozzle is actively printing.
