Product details
In use, this PTFE (Polytetrafluoroethylene) tube stands out as the critical component for maintaining the consistency of your 3D printer's filament flow. As the ultimate wear part, it endures repeated filament friction and the heat from the hotend block. This virgin Teflon model offers exceptional smoothness, reducing the strain on your extrusion motor, eliminating extruder skipping, and preventing under-extrusion issues. It is perfect for replacing the original tube in your remote (Bowden) system or serving as an insulating liner inside the throat of your V5, V6, or J-Head type print heads. Thanks to a strict dimensional tolerance of ± 0.05 mm, the filament remains perfectly straight without wavering, ensuring reliable printing of delicate or flexible filaments (such as TPU) and improving retraction sharpness. Designed to withstand a continuous operating temperature of 240°C, it ensures safe use with common filaments (PLA, PETG, TPU). Offered in 5 or 10-meter coils, you have a generous length for maintenance operations, provided you select the diameter suitable for your machine.
Compatibility and uses
This PTFE guide tube fits the vast majority of FDM 3D printers on the market using standard Pneufit fittings. Select your variant: for 1.75 mm filament, choose an inner diameter (ID) of 2 mm (2x3 mm or 2x4 mm version with reinforced wall). For 2.85 / 3 mm filaments, choose dimensions 3x4 mm or 4x6 mm depending on your print head. Easily cut to size using a sharp blade.

Usage advice
Team tip: cut the PTFE perfectly straight with a tube cutter. An angled cut leaves a gap in the hotend and creates clogs.
Presentation

Frequently asked questions
What is this tube used for?
To guide the extruder's filament to the hotend (Bowden) or to thermally insulate the filament within the hotend's groove.
What diameter for 1.75 mm filament?
You must select an inner diameter (ID) of 2 mm, which corresponds to the dimensions of 2x3 mm or 2x4 mm tubes.
What diameter for 3 mm filament?
You need to choose an inner diameter of 3 mm or 4 mm, corresponding to the 3x4 mm or 4x6 mm formats.
What is the difference between 2x3 mm and 2x4 mm?
The two guide 1.75 mm filament (ID 2 mm). The 2x4 mm has a thicker wall, thus more rigid: recommended for long Bowden setups as it better withstands the pressure from pneufits.
Can I print nylon or Polycarbonate?
This PTFE tube is optimal up to 240°C. Above 250°C (nylon, PC), equip your 3D printer with an all-metal heat break to avoid exposing the PTFE directly to heat.
Why is a tolerance of ± 0.05 mm important?
A tight tolerance keeps the inner diameter constant: the filament does not ripple during retractions, ensuring precision and surface quality.
