Clear PFA PTFE Bowden Tube 2x4mm for 1.75mm Filament

Clear PFA / PTFE Bowden Tube (2mm ID x 4mm OD) for 1.75mm Filament

Take the guesswork out of troubleshooting with the Clear PFA / PTFE Tube 2x4mm. Designed perfectly for 1.75mm filament, this transparent tubing allows you to visually track your material from the extruder directly to the hotend. Featuring ultra-low friction and high heat resistance, it guarantees smooth, slip-free extrusion while fitting perfectly into standard 4mm pneumatic fittings. (Priced per meter).

Product Description

Upgrade your 3D printer’s extrusion system with this premium Clear PFA / PTFE Tube 2x4mm. Designed specifically for 1.75mm filament setups, this transparent tubing offers a massive functional advantage over standard opaque white PTFE: full visibility. By allowing you to see the filament as it travels from the extruder to the hotend, you can easily spot filament runouts, broken strands, or grinding dust before they lead to a failed print.

Constructed from high-quality PFA (Perfluoroalkoxy, a highly transparent fluoropolymer sharing the same core benefits as PTFE Teflon), it delivers incredible low-friction properties and excellent temperature resistance. It ensures a buttery-smooth filament path, reducing stress on your extruder motor and minimizing stringing during retractions. With a precise 2mm inner diameter and 4mm outer diameter, it fits perfectly into standard PC4-01 (M10) and PC4-M6 pneumatic fittings found on RepRap, Rostock, standard Bowden machines, and custom DIY 3D printers.

(Note: Typically sold per meter. If ordering multiple quantities, it is cut as a single continuous piece).

Key Features

Transparent Design: Fully clear material allows for easy visual inspection of your filament path for instant troubleshooting.
Ultra-Low Friction: High-lubricity internal walls guarantee smooth filament feeding and highly accurate retractions.
Precise Dimensions: 2mm Inner Diameter (ID) and 4mm Outer Diameter (OD), perfectly sized for 1.75mm PLA, PETG, ABS, and TPU.
High Temperature & Chemical Resistance: Withstands the heat creep near your hotend’s heatsink without deforming.
Universal Fit: Drops right into any standard 4mm pneumatic fittings used in Bowden or reverse-Bowden extrusion setups.

Applications

Upgraded Bowden tube replacements for 1.75mm FDM 3D printers
Reverse-bowden setups for feeding direct-drive extruders (like Voron or custom toolheads)
Filament guide tubes spanning from custom dry boxes to the printer
Visible fluid or pneumatic air routing for CNC machinery and workshop tools
