  • 5 metre length gives 16.4ft of continuous tubing for 3D printers
  • 8mm inner diameter and 2.6mm outer diameter fit RepRap Rostock Kossel
  • Withstands -70 to +200°C for extreme temperature stability
  • Resists aqua regia and organic solvents for chemical durability

PTFE tube for 3D printers

This PTFE tubing has a 1.8 mm inner diameter and 2.6 mm outer diameter, supplied in a 5 metre length. It is intended as a guide tube for Bowden-style extruders on machines such as the RepRap Rostock and Kossel. The low-friction bore helps filament feed smoothly without binding.

Temperature resistance and chemical stability

The tube operates continuously from -70 °C to 200 °C, so it handles standard PLA, PETG and ABS printing temperatures with headroom to spare. PTFE resists aqua regia and organic solvents, meaning it will not degrade when exposed to common cleaning agents or filament additives. It is not suited for applications that exceed the 200 °C upper limit.

Lightweight construction and simple mounting

Weighing 38 g for the full 5 m roll, the tubing adds negligible mass to a moving gantry. The 2.6 mm outer diameter fits standard pneumatic push-to-connect fittings used on many 3D printer hot-end assemblies. No specialised tools are required to cut or install the tube. It is not designed for high-pressure fluid lines beyond typical Bowden extrusion forces.
