PTFE tube for 3 mm filament

This PTFE tube is designed for 3 mm filament with a precise 4 mm inner diameter and 6 mm outer diameter. The 9.84 foot length suits Bowden extruder setups on many desktop 3D printers. It is compatible with popular machines such as Anet, RepRap, Prusa and MendelMax models.

Low-friction PTFE handles heat and feed

PTFE material provides a smooth internal surface that reduces drag on 3 mm filament during retraction and extrusion. The tube withstands typical hot-end temperatures without softening, helping to prevent heat creep and jams. Its white colour makes filament movement easy to inspect visually.

White PTFE tube supplied in single length

The package contains one continuous 9.84 foot tube that can be cut to the exact Bowden length your printer requires. A 4 mm inner diameter and 6 mm outer diameter fit standard pneumatic push-to-connect fittings used on many extruder assemblies. The tube arrives new and ready to install.

Questions about this item

How do I install the PTFE tube on my 3D printer and what step is often missed?

Cut the tube squarely to length, push it fully into the hot-end until it seats against the nozzle, then secure the pneumatic fitting; the step often missed is trimming the end perfectly flat so filament does not catch on a bevel.

What maintenance or replacement will this PTFE tube need over time?

The PTFE liner degrades with heat cycling; plan to replace the tube when the inner surface shows discoloration, roughness, or when filament friction increases noticeably during extrusion.

What limit appears first during long prints with this 4 mm ID tube?

The 4 mm inner diameter is sized for 3 mm filament, so the first limit under sustained use is heat creep softening the PTFE and increasing drag on the filament.
