PTFE Tube for 3D Printers Bowden 1.75 mm – 5 m rolls 2/4mm

Low-Friction PTFE Tube for Bowden / Filament Guide

Made of industrial-grade PTFE (Teflon®), this tube optimises filament feeding in Bowden systems or as a filament guide with direct drive extruders. The highly polished inner surface reduces drag and helps prevent jams, grinding and under-extrusion, especially with delicate materials (PLA, TPU).

Key benefits

• Low friction: extra-smooth bore for consistent flow.
• Thermal stability: indicative range −60 °C / +260 °C.
• Tight tolerances & rigidity: less ovalisation and crushing on curves.
• Wide compatibility: 2×4 fits most PC4 push-fits; 4×6 for PC6 or protective routing.
• Professional documentation: technical data sheet and certifications on request.

Sizes – 5 m rolls

• 2 × 4 mm (ID × OD) – standard Bowden for 1.75 mm filament (OD 4 mm).
• 4 × 6 mm (ID × OD) – for systems requiring OD 6 mm (PC6).

Continuous length supply: buying multiples (5 m each) is delivered as one single piece for seamless routing.

Installation tips

• Square cut (90°) with a sharp blade; remove any burrs.
• Use gentle bends to keep resistance low.
• Check push-fit type: PC4 (OD 4 mm) vs PC6 (OD 6 mm).

Performance depends on tolerances and path design; for critical uses, refer to the technical data sheet and your printer specifications.
