Replacement PTFE Bowden Tube for 3D Printers — 2 Metres

Replace a worn or loose filament path with 2 metres of white PTFE Bowden tube for Creality, RepRap and similar Bowden-style 3D printers. Choose the internal and external diameter that matches your printer, then cut the tube cleanly to length with the supplied cutter.

Choose the correct tube size

• ID 2 mm / OD 4 mm — SKU 3B160
• ID 3 mm / OD 4 mm — SKU 3B161
• ID 3 mm / OD 6 mm — SKU 3B162

The tube is intended for 1.75 mm filament and is supplied in a 2 metre length per selected size. Match the tube to your existing couplers and hot-end interface rather than assuming every Creality or RepRap printer uses the same diameter.

Replace the Bowden tube cleanly

Unload the filament and let the hot end cool before working on the printer. Cut the replacement tube square, push it fully into each coupler or interface, and check that it cannot move in and out during retraction. A flat, well-seated connection helps reduce gaps and inconsistent filament guidance.

The source listing describes the tube as PTFE and gives a source-listed temperature range of −200 °C to 260 °C. Always follow the limits of your printer, hot end and couplers as installed.
