Description
Ensure smooth and consistent filament feeding with this high-quality 2x4mm PTFE (Polytetrafluoroethylene) tubing. Designed specifically for 3D printers using 1.75mm filament, this tubing acts as the essential conduit between your extruder and hotend. Its superior lubricity and non-stick surface drastically reduce friction, allowing the filament to glide through the guide path without resistance or binding.
Engineered for reliability, this PTFE tube exhibits excellent chemical and temperature resistance, capable of withstanding extreme conditions ranging from -180°C to 260°C. It is highly resistant to atmospheric aging, ensuring long-term durability, and is inherently non-flammable, providing an extra layer of safety for your 3D printing setup.
Key Features
- Ultra-Low Friction: Exceptional lubricity ensures minimal resistance, which is critical for consistent extrusion, especially in Bowden-style setups.
- Broad Temperature Range: Stable performance across a wide spectrum (-180°C to 260°C), making it suitable for most standard FDM printing materials.
- Chemical & Age Resistance: PTFE material does not degrade easily over time, maintaining its integrity even after long-term exposure to the atmosphere.
- Precision Dimensions: Standard 2mm inner diameter and 4mm outer diameter ensure compatibility with the majority of popular 3D printer hotends and extruders.
Applications
- Filament Guide/Bowden Tube: The gold standard for guiding 1.75mm filament from the extruder to the print head.
- Hotend Liner: An ideal replacement part for hotends that require an internal PTFE liner to maintain smooth filament flow.
- DIY Upgrades: A must-have maintenance item for resolving under-extrusion issues caused by worn-out or kinked guide tubes.
Package Includes
- 1 x PTFE Teflon Tubing (1-meter length)
