Unique-Bargains PTFE Transparent Tubing 3mm x 4mm 5m 16.4ft electrician tool
PTFE tubing with 3 mm inner and 4 mm outer diameter, supplied in a 16.4 ft coil, withstands -70 °C to +200 °C and resists aqua regia and organic solvents
- Handles extreme cold to 70 below and heat to 200 °C
- Resists aqua regia and all organic solvents for chemical durability
- Non-stick surface with high lubricity reduces friction in fluid paths
- Excellent electrical insulation suits wiring and electronics applications
- Five-metre transparent PTFE tube weighs only 60 grams
3mm PTFE tubing for 3D printers and electrical work
This transparent PTFE tube has a 3mm inner diameter and 4mm outer diameter supplied in a 5 metre length. It suits 3D printer Bowden setups and general electrical insulation tasks where chemical resistance matters. The material handles continuous temperatures from minus 70C to plus 200C.
Thermals noise and power draw
PTFE tubing is a passive component so it draws no power and produces no noise. Its working range of minus 70C to plus 200C means it remains stable inside heated chambers and near hot-end assemblies. The low-friction surface reduces filament drag without active cooling.
Replaces worn Bowden tubes and generic PVC sleeving
Swap this in when an existing Bowden tube shows interior scoring, discolouration or increased friction that causes under-extrusion. The jump is worth it if the current tubing cannot survive repeated 200C cycles or exposure to solvents. Buyers needing an inner diameter larger than 3mm or a length shorter than 5 metres should look elsewhere.

Questions about this item
How do I cut and fit the 3mm inner diameter PTFE tubing without crushing it?
Use a sharp blade to cut the 5m length cleanly, then push the 4mm outside diameter tube straight onto the fitting; twisting or excessive force deforms the 3mm bore and restricts flow.
What wear or replacement should I expect with the PTFE tubing over time?
The tubing resists aqua regia and organic solvents, so chemical degradation is minimal; inspect periodically for surface abrasion or kinks that reduce the 3mm inner diameter, and replace the affected section if flow drops.
At what temperature does the PTFE tubing start to lose stiffness during continuous use?
The material is rated from -70C to +200C; above 200C the tube softens and can collapse under pressure, so keep sustained operating temperature below that limit.
