PTFE tubing for 1.75 mm filament

The white PTFE tube measures 1.5 metres (4.92 feet) with a 2 mm inner diameter and 4 mm outer diameter. It is manufactured to tight tolerances so 1.75 mm filament feeds smoothly from the extruder to the hotend. The material is slippery and rigid enough to hold a gentle arc without kinking during normal printer operation.

Replaces worn or compressed stock tubing

Over time original bowden tubes develop internal ridges or ovality that increase friction and cause under-extrusion. Swapping to a fresh length restores consistent filament flow and reduces the frequency of nozzle clogs. The upgrade is worthwhile when retraction settings can no longer compensate for the degraded tube surface.

Maintains low friction during long prints

PTFE resists heat creep and chemical attack from common filaments, so the inner surface stays smooth over extended sessions. The tube holds its shape under the continuous push-pull of retraction cycles, preventing the gradual binding that soft or undersized tubing develops. It remains dimensionally stable across the temperature range used by typical 1.75 mm 3D printers.

Questions about this item

What inner and outer diameters does the 1.5 m PTFE tube have for 1.75 mm filament?

The tube has a 2 mm inner diameter and a 4 mm outer diameter, sized for 1.75 mm filament.

How do I install the PTFE tube so it keeps a smooth arc from extruder to hot-end?

Cut the tube square, push it fully into the pneumatic couplers on both ends, and secure the locking clips so the tube cannot retract under pressure.

When should I replace the PTFE tube on my 3D printer?

Replace it when the inner surface shows wear, discolouration, or when filament starts to catch during extrusion.
