Authentic Capricorn Bowden PTFE Tubing XS Series 1M for 1.75mm Filament with PTFE Teflon Tube Cutter, 2X PC4-M6 Extruder Fitting, 2X PC4-M10 Hotend Fitting for Ender 3 V2/3/3 Pro/CR-10 3D Printers

Works as advertised and was easy to install as well. A great and simple upgrade for increased realizability. Included tube cutter worked just fine and I still had tubing left over for replacement use down the line.

Not sure this is any better, but seems nice and on our second one....

The cutter worked without deforming the tube and my 3d printer is back in business.

Capricorn is well worth the money and the cutter made it alot easier to get a straight cut.

Bought this for my Ender 3 Pro, as the stock PTFE tubing was gunked up in the hot end, near the nozzle. Used this Capricorn for the Luke Hatfield Mod and my printer is running better than before!

It seems like a ton of people in the 3D printing community recommend this tubing because of its tighter inner diameter spec leading to more consistent moments from the extruder. In theory, and when using filament that is exactly 1.75 mm or less throughout the entire spool, this is very true. However, the vast majority of brands will have a variance that goes a little (or a lot) over that 1.75 mm spec at some point in the spool, which is almost guaranteed to cause a jam with this XS tubing. Even if there is only one spot on the entire 300 meter spool that is slightly out of spec, that is enough to cause friction in the tube and for it to cause a jam. At first, I refused to believe that the tubing was causing the issues and thought I might have an extruder issue. I thought maybe the extruder spring was a little too tight causing it to squish the filament while it pushed it into the tube, making it press against the inside of the tubing. So, I replaced the entire extruder assembly and tried many different springs. No change; my machines were still jamming on a daily basis. I tried many different filament brands from Overture, Hatchbox, eSun, Amolen, etc... and all would, given enough time, eventually cause jams on both of my printers with the tubing installed. I also bought some of this XS tubing for my coworker and he experienced the exact same issue. The issue has only gone away when I replaced the tubing on both of my printers with slightly less tight inner diameter spec of 2.0 mm instead of the 1.9 mm this tubing comes with. Ive been printing nearly non-stop now for four days and have yet to experience another jam. Before you disregard this review with, Well, Ill just make sure my filament is to the correct spec. Understand that, even with the filaments that would measure at or close to 1.75 mm in the first few meters I checked, there was no way I could check every mm of the entire 1 Kg spool. All it takes is one spot to be too far out of spec to cause friction in the tube, leading to your extruder forcing the filament through, causing more friction, resulting in your extruder gear crushing the filament to the point it will no longer move at all. Its a snowball effect of friction. Aside from the inner diameter spec being too tight (which is the whole point of this tubing), everything else was fine. The quality of the tubing was great, the consistency of the tubing itself appeared to be flawless, the cutting tool it came with worked well, and the couplers were a nice upgrade over stock. However, almost none of that matters when the 1.9 mm tube diameter shouldnt be used at all for printing if you care about printing reliability.

I received the package open and it was missing the fittings. Now I have to wait longer for the replacement.

The tubing and couplers are great, but the tubing cutter was not included.

No issues, high quality connectors

Capricorn is hands down the best name in printing parts. The accuracy of this bowden is amazing, and it is used by most professionals.
