Unique-Bargains PTFE Tubing 3mm ID 4mm OD 1M White

SKU CH-7D1N-Z2VN3

PTFE tubing with 3 mm inner and 4 mm outer diameter, supplied as a 1 metre length for 3D printer filament guidance

  • 3 mm inner diameter matches Bowden set-ups
  • 4 mm outer diameter fits standard push-fit couplers
  • PTFE withstands -70 °C to 200 °C
  • Chemically inert against solvents and aqua regia
  • Low-friction surface reduces filament drag

Tubing dimensions and material

This PTFE tubing has a 3 mm inner diameter, a 4 mm outer diameter and a 1 M length. It weighs 15 g and is supplied as a single white tube. The material is PTFE (Poly Tetra Fluoro Ethylene).

Who this suits and who it does not

Suitable for 3D‑printer guide tubes such as RepRap Rostock Kossel and CTC 3D Creator. Not for buyers who need a different inner diameter, a longer continuous length or a non‑PTFE material.

Temperature range and chemical resistance

The tube handles continuous temperatures from ‑70 °C to +200 °C and resists aqua regia and organic solvents. Its high lubricity and non‑stick surface help filament feed smoothly.

Questions about this item

How does the 3 mm inner diameter perform inside a 3D printer extruder?

The 3 mm bore provides a low-friction path for filament, and the PTFE material resists temperatures from -70 to 200 °C without degrading.

What does the PTFE material withstand in daily printing use?

PTFE handles continuous exposure up to 200 °C and resists common solvents, so the tube stays dimensionally stable during long prints.

Will the 4 mm outer diameter and 1 m length fit my Bowden setup?

The tube measures 4 mm OD and 1 m (3.3 ft) long, weighing 15 g, and can be cut to the exact run needed for most Bowden extruders.
