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

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.

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.

Product was easy to use and described.

Muy buen producto!!

It is exactly as described.

Ideal for my printer. Be sure to measure the diameter of the old tube. I lucked out and the tube I ordered was the correct size.

Good value for when you need to thread filament from a dryer box to the printer.

This product meets my expectations and is "as advertised". I purchased it as a spare for my Bowden type printer. I fully inspected the product for "grip-ability" of the ends in the end fittings and smoothness of filament passage through the tubing. All fits are very satisfactory. The current tubing on my printer appears to be clear vinyl, which clearly shows the filament inside, However, it is "softer" and seems to have more internal drag than PTFE.I am ready if I have to make a change as I have noticed the original tubing had once become loose in the fitting at the stepper end. Filament retracts were causing a 1 to 2 mm movement up and down in the fitting. Any movement of the tubing in a fitting is unsatisfactory when printing. I cut the worn end back and replaced the grip fitting. Then ordered this product as a tubing replacement. PTFE seems to be the standard applied material for Borden tubing. If I see slipping again I will know vinyl is truely inferior and will be prepared to switch to this tubing.
