PTFE Teflon Bowden Tube for 1.75 Filament (2.0mm ID/4.0mm OD) 1.5 Meters – White Connector Tubing for 3D Printer

The OD is a little larger, but works great.

I used about a quarter inch of this tube along with a 3D print of a tiny bracket I designed, two short M3 screws, and locking nuts to fix a design flaw in a spool heater and filament dehydrator I also purchased on amazon. While I'm not sure if this is the same sized tube used internally for my printer, I do not regret the decision. Since I made the modification, the spool filament feeder has worked flawlessly with no binding and not fallen out every time I change spools and gotten lost like the ones that came with the heater. I keep the tubing around to replace the section currently in use for when it eventually wears out. The price was good and delivery was quick. I would order this again.

The AMX3d PTFE Teflon Bowden Tube is a high-quality and affordable option for anyone looking to upgrade or replace their existing 3D printer Bowden tube. The tube is designed to work with 1.75mm filaments, and it is made from PTFE Teflon, which is a durable and heat-resistant material that ensures smooth filament feeding and consistent extrusion.One of the things I appreciate about this Bowden tube is its precision and accuracy. The tube has an inner diameter of 2mm and an outer diameter of 4mm, which ensures that it fits snugly and securely into the hot end and extruder of your 3D printer. This reduces the likelihood of filament jams or clogs and ensures a smooth and reliable printing experience.The tube also has a low friction coefficient, which ensures that the filament moves smoothly through the tube and reduces the chances of filament grinding or wear on the tube itself. This improves the overall print quality and reduces the likelihood of extrusion issues.Overall, I would highly recommend the AMX3d PTFE Teflon Bowden Tube for 1.75 Filament for anyone looking for a high-quality and affordable replacement or upgrade for their 3D printer Bowden tube. It is well-designed, durable, and ensures smooth filament feeding and consistent extrusion, which results in high-quality 3D prints.

easy to replace the old one

I am using this for routing filament from my dry boxes to the printer. I have not used it where it is going to the hot end (bowden extruder style of printer) so cannot comment on how well it deals with heat. For my application it seems a reasonable quality tube, it cuts cleanly and is easy to insert into a fitting. It is however a little stiffer than others I have used and ideally I would like it a little less stiff. This could be a positive in some applications.

Works fine. Filament seems to glide through without issues.

Works great, easy tonsee filament.

I recently picked up the AMX3d PTFE Teflon Bowden Tube as a replacement for my Sidewinder X2 3D printer, and it's been a perfect match. The tube's dimensions (2.0mm ID/4.0mm OD) are ideal for the 1.75 filament, ensuring a smooth and consistent feed with no snagging or friction. This 1.5-meter tube was incredibly easy to install and has significantly improved my printing process. The white color even adds a neat, professional look to the setup. For anyone with a Sidewinder X2 or a similar 3D printer, this Teflon tube is a great choice for a hassle-free printing experience.
