About This

• 【Seals Idle Nozzle During Dual-Nozzle Printing】 The nozzle shutoff for Bambu Lab H2D and H2C is designed to seal the nozzle when it is in a non-operating state. During dual-nozzle printing, the idle hotend remains at high temperature, which can cause melted filament to slowly drip out. This genuine FAC125 nozzle seal physically blocks the nozzle tip, stopping filament flow and keeping your print surface clean from unwanted drips
• [Essential for dual-nozzle printing quality] For bambu lab h2d and h2c owners, the h2c nozzle blocker is a critical component for multi-color and multi-material printing. Without proper sealing, melted filament from the idle nozzle can drip onto your print, causing surface defects and ruining layer adhesion. The flow blocker for h2d h2c ensures each nozzle only extrudes when actively printing
• 【High Temperature Resistant Construction】 Made from durable plastic, metal, and silicone composite materials, this Bambu Lab nozzle seal withstands the extreme heat of the hotend environment. It maintains its shape and sealing performance even after hundreds of hours of high-temperature printing with engineering-grade filaments like ABS, PC, and Nylon
• 【Easy Replacement with Magnet Bracket System】 This nozzle seal replacement works with the magnet bracket installed on the toolhead. The nozzle shutoff is held in place by magnets and controlled by a lever that moves it between left and right nozzles. Installation takes minutes following Bambu Lab Wiki guides, with MG2.5-8 screws included
• 【Long Term Maintenance Spare Part】 This kit gives you spare replacements for future maintenance. As a consumable component, this Bambu Lab H2C nozzle seal should be replaced when you notice wear, deformation, or poor sealing performance. The dual-nozzle seal for Bambu H2D ensures consistent performance print after print
