Polybox ptfe adapter

A streamlined, threaded adapter designed to connect a standard PTFE Bowden tube directly to your Polymaker Polybox or PolyDryer.

Instead of leaving the filament exposed, this adapter plugs directly into the original rubber seal/grommet of the Polybox. It features a custom-modeled internal thread to accept a standard pneumatic fitting, allowing for a fully enclosed, friction-free filament path from the drybox straight to your printer's extruder or AMS.

Key Features:

🔌 Direct Integration: Plugs perfectly into the stock rubber seal of the Polybox—no permanent modifications required.
🔄 Fully Enclosed Path: Keeps your filament protected from ambient moisture and dust along the entire routing path.
⚙️ Precision Threads: Modeled to tightly accept standard pneumatic Bowden fittings.
