FYSETC PTFE Teflon Tubing 1M/39.3 Inch ID-1.9mm OD- 4mm for 1.75mm Filament -Feeder Hotend Part for Reprap Rostock Bowden 3D Printer Extruder-Blue

I received a faulty piece of tubing, the seller sent me another piece that works fine. So, anyone who buys this(which I do recommend) should run a good piece of filament down the tube by hand several times to make sure there is no binding before installing the new bowden tube. I could have saved myself a big headache. See below for my original review.---------------------------------------------------------------------------------------------------------------------------------Looks nice, no noticeable burrs. Binds severely, causing massive under-extrusion. I tried pushing filament through it with ptfe lubricant, it was too tight. I measured my filament diameter, I get no higher than 1.77, this should be fine. My extruder stepper is clicking constantly and not feeding properly. Had to put an old tube back on to keep printing.

Upgraded my printer from the cheapo PTFE tube I had and am very happy with it. It feels quality, slippery, and rigid enough to maintain a nice kink free arc from the extruder to the hotend. ID is 1.9 and I was able to get good results with TPU, printing slowly at 30mm/s (didn't try higher), all over a 60CM long bowden.Only complain is that it's 100% opaque so its harder to diagnose feed issues, but since the competition Capricorn XS is also opaque I am giving it 5 starts.FYSETC is a Chinese vendor that has a store also on Aliexpress and has good reputation in general. I am glad to see their products here on Amazon which provides faster delivery and still at a reasonable price.

Just as good, if not better than the leading competition. You know who i'm taking about. Something that starts with a "C". Seriously, I've gone through my share of PTFE Tubing and this one is great. It's lasted a long time at normal print temperatures.

**Seller Refunded Money is I give 3 stars** This tubing is so tight the filament jams half way to the hot end.. it’s like there’s pinch spots on the inside of the tube every inch or so.. I tried all 6 spoils all 1.7.. they all jammed.. so this tubing is literally useless lol bad batch? Either way..1star.

the tube works as it’s suppose to with no problems at all. Like in the other comments , it’s enough for two pieces. Great price great product . The sellers customer care team are very helpful and honest . I will be buying from them again. (Definitely recommended)

Not good at all. Leaves burnt residue in the tube that causes clogs too frequently. I print between 185 and 200 so there is no reason for it to do this. Ive tried it several times over the last few years and always get the same result. I do not have these issues with another brand. Capricorn

Not sure if this tube is actually tighter than other tubes

There is plenty of material to make two for the Ender 3. The smaller inner diameter allows for less binding and smoother operation and the ability to print with flexibles.

Macht was es soll. Schnelle Lieferung und Einbau is auch einfach.Kann ich nur empfehlen.
