PTFE Teflon Bowden Tube for 1.75 Filament PC4-M6 Fittings (2.0mm ID/4.0mm OD) - (1Meters) Teflon Tube…

I bought it for a small project with my elegoo neptune 2, but it turned out to serve me better than the original

if you are using this for 3D printing filament, you will need to make sure it feeds absolutely straight in, the inside seems to scrape the filament going in and will cause problems down the line. I designed a guide fitting for my drybox that this screws into and it does work great after that.remember, your filament is coming off the roll in a circular fashion, let it keep those wide bends if you are using it to feed into another direction. tubing works ok.

One of the PTC fittings worked well on my extruder, but the threads on my hot end weren't the same size (Creality printer). The bigger 'tab' makes life much easier, and removing it is MUCH easier than my prior bowden tube. In my case I have enough for another as well.

Good as the original and easy install

I can't vouch for the nozzle, but it cut well and reformed to line the hot end of my FlashForge Finder. Cut to 45 mm, I had no use for the nozzle which is completely different for my printer. The tube was a good deal on its own for all my future PFTE pipe replacement needs.

Great for 1.75mm 3D printer filament!I needed to replace my bowden tube. I used the rest to attach an external filament enclosure.Great product. Will buy again to build my own printer!

Worked perfectly to fix my 3d printer

Man do I wish I had this kit from the beginning. I replaced the awful small bowden fittings on my Ender-2 with these and absolutely love them. They're nice and heavy duty and have not failed me once.
