2x4 mm PFTE Teflon Tube 50 cm for 3D Printers - Blue

The "2x4 PTFE Teflon Tube Blue" is a high-temperature resistant filament guide tube commonly used in 3D printers. Here’s a breakdown of its features and applications:

1. Material Features

• PTFE (Polytetrafluoroethylene): Also known as Teflon, PTFE is a material with excellent heat resistance and a low friction coefficient. It ensures smooth passage of the filament to the printer’s hot end.
• 2x4 mm Dimensions: The tube has an inner diameter of 2 mm and an outer diameter of 4 mm, making it ideal for use with 1.75 mm filament.

2. Color

• Blue: This tube typically comes in blue, providing both an aesthetic look and compatibility with most 3D printers.

3. Applications

• Filament Guide: The PTFE tube guides the filament smoothly from the extruder to the hot end, reducing friction and preventing filament jamming.
• High-Temperature Resistance: PTFE is highly heat-resistant, making it suitable for high-temperature filaments such as ABS and PETG.
• Bowden 3D Printers: This tube is particularly useful for Bowden-type 3D printers, where the extruder is positioned away from the hot end. It enables smooth filament movement over longer distances.

4. Advantages

• Low Friction: PTFE tubes have a low friction coefficient, allowing for smooth filament passage to the hot end.
• High Durability: With its chemical resistance and durability, PTFE is long-lasting and reliable in use.
• Easy Installation and Compatibility: The 2x4 mm dimensions make it compatible with standard filament diameters and easily installable in most 3D printers.

This PTFE tube enhances the 3D printing process by preventing filament jams and contributes to more precise and consistent prints.
