10M PTFE Teflon Bowden Tube (2.5mm ID × 4mm OD) for 1.75mm Filament
Product description
Designed for 1.75mm filament systems, this kit supplies 10 meters of PTFE bowden tubing with an inner diameter of 2.5mm and an outer diameter of 4mm. A compact precision cutter is included to trim the tubing cleanly for perfect seating in fittings.
Constructed from high-grade PTFE, the tube offers a slick internal surface that lowers friction and helps keep TPU, TPE, PLA and other 1.75mm filaments moving smoothly through extruders. The material reduces the chance of snags and filament buildup for more consistent prints.
The tubing tolerates temperatures up to 260°C without losing form or function, ensuring stable performance during long prints and with a range of filament types. It’s suitable for both direct-drive adaptions and bowden setups where thermal stability matters.
Built to resist abrasion, cracking and deformation under pressure, the tube holds up to routine handling and re-routing. Its flexibility allows gentle bends without collapsing while still offering good shape retention.
The included cutter delivers straight, square cuts that help eliminate misalignment and filament jams. Typical uses include tidy filament routing for multi-spool feeders, connecting dryers to feeders, extending run lengths, or replacing worn bowden segments.
Pros
- Long 10 m length for multiple runs
- Low-friction PTFE surface reduces clogs
- Precision cutter yields clean, square ends
Cons
- May not suit specialty high-temp setups beyond 260°C
- Not reinforced for extreme mechanical stress
- Requires careful bends to avoid premature wear
VerdictThis 10-meter PTFE tube kit is a practical, cost-effective upgrade for anyone using 1.75mm filament. The diameter (2.5mm ID × 4mm OD) fits common push-fit connectors and feeds flexible and rigid filaments with minimal drag. The included cutter produces square, clean ends that reduce seating and feeding issues. It withstands temperatures up to 260°C and resists abrasion and deformation, making it a

Used to extend dryer connections
Needed longer lines between my dryer box and Snapmaker U1 feeders. This tube worked well and resolved the gap.

Cuts are the highlight
The cutter is the MVP—makes tidy ends every time. The PTFE itself performs as expected.

Performs as described
Does exactly what it should. No surprises.

Great for bulk replacements
Basic bowden tubing but plenty of length. I don’t need premium stuff for all runs, so this is fine for everyday use.

Excellent value for frequent changers
I keep spares on hand and this kit gives a lot of tubing for the cost. It lasts through moves and re-routing when I change printer setups. I’ve bought this multiple times and haven’t been disappointed. Avoid tight bends to extend service life.

Ample length and easy to work with
Comes with plenty of tubing and the cutter helps get clean, round ends. Flexible without kinking easily and it improved filament handling on my machine. Good overall quality for the price.

Solid PTFE tubing with handy cutter
Good value and the cutter is genuinely useful. Fits my Bambu Lab AMS hardware and feeds reliably. I’d buy this again.

Exactly what I needed for multiple AMS runs
Picked this up to tidy the filament paths on my Bambu X1C after installing several AMS units. Stock tubing wasn’t enough once I added more spools, so the extra length here was perfect. The diameter matches push-fit fittings and filament slides through with no obvious drag. The cutter makes crisp, square cuts which is important for proper seating in the connectors. Plenty of tubing for my four-AMS layout and handy extras for future changes.
