1 Meter 2x4 mm PTFE Tube for 3D Printer

The 2×4 mm PTFE Tube for 3D Printer is a key component in Bowden extruder systems, designed to guide 2 mm filament smoothly to the printer nozzle. This Tube for 3D Printer is made from high-quality polytetrafluoroethylene (PTFE), a material known for its ultra-smooth surface, minimal friction, and excellent resistance to heat and chemicals.

The inner surface of the PTFE Teflon Tube for 3D Printer is non-stick, allowing filament to move freely without clogging or excessive friction. This reduces pressure on the extruder and improves 3D print quality. Its high flexibility also enables the nozzle to move freely without putting stress on the filament, ensuring consistent extrusion.

One of the standout features of this Teflon hose is its exceptional heat resistance. It can withstand temperatures from 190 °C to 280 °C without deformation or performance loss. Additionally, its chemical resistance to acids, strong oxidizers, and solvents ensures long-lasting durability and reliability.

This 2 mm Filament Guide Tube is compatible with popular 3D printer brands such as Creality, Prusa, Anycubic, and other common models. Made from environmentally friendly materials and free from harmful additives, it provides safe and reliable operation for all your 3D printing needs.

How to Use the PTFE Teflon Tube for 3D Printer

Precise Cutting:

• Before installation, use a dedicated PTFE cutter or a sharp blade to make a clean, straight cut. This ensures smooth filament flow and reduces printing issues.

Connecting to the Bowden Extruder:

• Insert one end of the tube into the extruder’s pneumatic fitting. Make sure the tube is fully seated to prevent leaks.

Connecting to the Hotend:

• Attach the other end of the tube to the hotend fitting, ensuring it is properly secured. Some printers may use a metal or pneumatic coupler for this connection.

Checking Filament Flow:

• After installation, feed filament through the tube to ensure it moves smoothly without resistance. If there’s an issue, check for kinks or blockages.

Maintenance and Replacement:

• Over time, the tube may wear out or become clogged. Replacing it restores performance and improves print quality. Keep the tube clean and free of dust to maintain smooth operation.

Note: Some 3D printers use high-quality PTFE tubes like Capricorn PTFE to increase precision and reduce friction. These are ideal for sensitive filaments such as TPU and PETG.
