Unique-Bargains PTFE Tube 26ft White 4mm ID 6mm OD 3mm Filament

Precision PTFE tubing for 3 mm filament

This white PTFE tube is manufactured with a 4 mm inner diameter and 6 mm outer diameter to guide 3 mm filament cleanly through a Bowden extruder. The tight internal tolerance reduces friction and helps prevent jams during long prints. It suits a wide range of desktop 3D printers including Anet, RepRap, Prusa and MendelMax machines. The material resists heat and chemical wear inside the hot-end assembly.

26 ft continuous length gives ample headroom

At 26.25 feet the single piece covers multiple printer builds or several full Bowden runs without joins that can restrict flow. The length handles direct-drive conversions and tall delta frames comfortably. Very large enclosed chambers or dual-extruder setups with long tube runs may require a second length. The tubing remains flexible enough for tight routing yet stiff enough to resist kinking.

Pure PTFE construction with clean-cut ends

The tube arrives as one 8 metre white length ready to trim to exact Bowden distances. PTFE withstands typical hot-end temperatures and resists degradation from common filament additives. No fittings or collets are included so builders must supply their own push-to-connect couplers. The smooth bore and consistent diameter simplify calibration and reduce retraction artefacts day to day.
