PTFE tube for 1.75 mm filament

This PTFE tube is a replacement Bowden guide for 3D printers that run 1.75 mm filament. The 2 mm inner diameter gives the filament a precise, low-friction path from extruder to hot-end. It suits owners of Anet, RepRap, Prusa or MendelMax machines and most other printers using the same bore size. The red colour makes the tube easy to spot during maintenance.

Best for direct Bowden upgrades

Makers who need a 3.2 ft length of 2 mm ID tubing will find this a direct fit. The PTFE material resists heat and chemical wear in typical printing environments. Printers that use 1.75 mm filament with a standard 4 mm push-fit coupling are the intended users. Builders whose extruders demand a different inner diameter or a longer continuous run should look elsewhere.

2 mm inner diameter decides fit

The single specification that determines compatibility is the 2 mm inner diameter matched to 1.75 mm filament. If your hot-end or coupler requires a larger or smaller bore, this tube will not seal correctly. The 4 mm outer diameter and 3.28 ft length are secondary; the ID is the critical measure.

Questions about this item

How does the 2 mm inner diameter work with 1.75 mm filament?

The 2 mm bore leaves a small clearance around 1.75 mm filament, letting it feed smoothly without binding in most Bowden setups.

What does the 4 mm outer diameter limit when routing the tube?

A 4 mm OD fits standard 4 mm push-to-connect fittings and keeps the tube narrow enough for tight cable chains on common printers.

Will the 3.2 ft length reach from my extruder to the hot-end?

At 3.28 ft the tube covers typical Bowden runs; measure your own path and trim the PTFE to the exact length you need.
