PTFE Teflon tubing 10ft- 2mm ID X 4mm OD for 1.75 Filament Bowden 3D Printer -Allen Tech PTFE Teflon Tube

Tubing works well in my A1 Mini 3D printer and AMS Lite. Plenty of it so I don't feel bad about wasting it if I cut it wrong. Seems to be holding up well for the last few months.

The PTFE Teflon tubing with a 2mm ID and 4mm OD for 1.75mm filament proves to be an indispensable component for 3D printing enthusiasts. The 5-foot length provides ample material for various projects, ensuring a smooth and consistent flow of filament. The high-quality construction of this tubing, known for its non-stick properties, minimizes friction, preventing clogs and enhancing the overall reliability of your 3D printing setup. Whether you're a novice or an experienced maker, this PTFE tubing is a crucial accessory for achieving precise and uninterrupted filament extrusion.

I needed to replace the small PTFE tube in my Ender 3 KE upgraded hot end. This tube fit perfectly and dimensions matched the original. I only needed a small piece, but the extra will be nice to have on hand. Highly recommended!

Running on a Bambu Lab P1 Series. It's pretty much more see-through than other PTFE white tubes, very useful when loading/unloading. I use it with normal 1.75mm filament, absolutely 0 drag its very slick. Wouldn't suggest to print TPU with this as its not tight fitting, for the diameter mentioned above, but for pretty much anything else its a dream for printers extruder parts. No stress on components when pulling at all. HOWEVER, it is very easy to kink/bend.. if you try. But if accidentally create a bend they give you so much ft just cut and use more. Thermally is ok, I print ASA and chamber temps get 120F inside, and the filament in tube does not feel that heat so it is stiff while it runs through as should be. 4/5 starts - (due to tube not being as stiff, not a serious issue at all, but can't say it's perfect)

I was having trouble with my Bambu P1S, poor first-layer adhesion. Finally tracked it down to too much resistance with the more expensive tubing I had installed. Swapped to this 3mmx4mm and the filament has far less resistance. Just what I was looking for. Yes, this can kink easier than the thicker tubing but that has not been an issue for me. Also, the thinner tubing makes it easier to see the filament in the tube. The packaging is large and thus the tubing is not wound tight, this causes less curve memory when you install it. Overall very happy with the quality and value.

Some 1.75mm Filaments for 3D printing are NOT 1.75mm some are actually up o 2.1mm meaning your common 4mm OD / 2mm ID tube won't cut it. Glow in the dark, word, carbon fiber, etc. can be greatly varying diameters and the run of the mill PTFE tubing won't work. I bought this and works fine with one caveat; make sure the spring teeth in you hot end assembly is tight of the thin PTFE tubing that this is may pull loose.

My printer came with 2.5mm ID tubing. I was adding some more filament spools so needed more tubing. I ordered this 3mm ID tubing thinking that would give me less friction, but my filament really drags in this tubing. It's hard for me to pull regular 1.75mm filament through less than 4 feet of this. I'm surprised the printer can do it.

I topped mounted my AMS lite on my Bambu Lab A1, but I found the existing tubing for the back filament to be a little bit too short. I was able to use this to create the perfect length and its been working great for my A1. My P1 tubing was in need of replacement, especially since I have been doing a bunch of glow in the dark filaments which destroyed the interior lining of the tubing. This worked perfectly as the replacement, I was able to cut a custom length that allowed a bit more length, which makes it easier to load from an external spool.

Works well low friction reverse Bowden tube.

Very thin but very low resistance for pulling filaments

As described, matches the listed specifications

Great quality, used to restore a 20+ year old espresso machine.

No problems, working well.
