PTFE Teflon Tubing 5ft Long, 2mm ID X 4mm OD For 1.75mm Filament Bowden 3D Printers, Translucent, Extreme Temperature Range -454F To 500F, Ultra Low Friction, Durable And Flexible Tubing For Smooth Filament Feeding
✔️ 2 mm ID x 4 mm OD, 5 ft length, translucent, FDA-listed
This PTFE Teflon tubing is a low-friction, high-temperature feed tube designed for 1.75 mm filament Bowden setups in desktop 3D printers. It keeps filament moving smoothly through the hotend and along the drive path, reducing feeding resistance and improving print consistency in hobby builds and professional setups.

💡 What is PTFE Teflon tubing used for in Bowden extrusion systems?
A handy feed tube that minimizes friction and heat transfer along the filament path.
- It provides a smooth interior surface for consistent filament feeding
- It withstands high nozzle temperatures up to 500°F (260°C) without degrading
- It resists acids, alkalis, and most solvents for long life in tough environments
- It is FDA-listed material suitable for contact surfaces in food-grade or lab settings
