Warranty Information
3 Months Warranty - Our warranty covers any and all defects with the product. If your product fails or has problems within the warranty period you can contact our support team by using the Contact Us link. Technical support is limited to the scope of the product itself and not your entire machine.
Damage/Failure due to improper installation, improper usage, failure resulting from an issue with the machine the product is installed on, 3rd party products connected to our product, and/or modification of the product are not covered under warranty.
In general using PTFE above 260C can cause “off-gassing” that can be harmful to small animals and birds, temps above 275C may shorten the life of our tubing. If you are using this in the melt zone on your printer please read the following guide on PTFE safety precautions (applies to ALL PTFE tubing, not just ours): PTFE Safety Precautions – ALL PTFE & ToughTube

I run a V6 hotend and wanted to print ABS. In order to do so I needed to bump my temps up above 240C and felt that the stock PTFE tubing wouldn’t meet my needs. Since I have small animals that could be affected by off-gassing I upgraded to the tough tube. Now I have peace of mind with running to 250C no problems.

This is the first upgrade to every printer I bring onto my printer farm. I feel it is an essential upgrade and this product surpasses every capricorn clone that I’ve come across. Consistent internal diameter, great temperature resilience and amazing product support (not that it’s needed, this tube wont give you issues)

This is great for printing higher temps with a stock creality hotend. It also reduces the slop in the bowden tube there by reduce your retraction settings.

Great ptfe tubing to replace on my stock ptfe on my e3 pro. Now able to print higher temp filament . Does just as good as my Capricorn on my ender 5 but a lot cheaper. Worth every penny

Tubing is nice, I replaced some capricorn tubing on my CR-20 Pro. Seems just as good if not better at a lower price.

Fitted to an Ender-3 and filament is very tight in this tube. Too much so in my opinion compared to slightly oversized stock tubing. Tried several brands of filament. Returned to stock.

You should check your filament and the tubing diameter. The filament should be 1.7-1.8mm and the tubing spec is 1.9mm +/- 0.05 (so 1.85-1.95mm at most). If the filament is out of spec then it needs to be changed and if the tubing is out of spec then contact our support. You also need to cut the tubing with a proper PTFE cutter and do not use flush cutters as it will crimp the tubing and cause it to hang up on the filament.

I have tried to buy generic PTFE tubing from other websites and they all somehow ended up failing, i finally got this for my five creality printers and i haven’t had any problems since then. I highly recommend this.

What’s the tolerance on the OD of this tubing? I’ve had cheaper tubes run 4.1mm and that’s too tight to work in a PTFE heat break.

Ours is no larger than 4.05mm at worst. All the samples we’ve taken over the years fall within 3.98-4.05mm.

Are there any special steps you should take when installing this to make sure it seats properly against the nozzle?

Make sure your PTFE fitting is in good shape and actually holds the tube.
Cut the end with a PTFE cutter before inserting to ensure a flat end.
Then before inserting the tube screw in your ptfe fitting all the way and then back it out 1/4 turn.
Heat the hotend to 240C and then insert the tubing firmly until it stops.
Then tighten down the PTFE fitting. This will lock it all in.
If you have to remove the tubing in the future make sure to unscrew the ptfe fitting 1/2 a turn before pressing the release on it.

Daniel Davis (verified owner) –
ordering another few lengths of this, got it to replace the stock tube on my CR-10. But since putting it in I’ve been having constant blockage in the end of the tube where it meets the nozzle inside the hotend. I’ve never operated it above 220 C, I’ve confirmed that it’s fully flush against the nozzle and is as close as I can get it to 90 degrees with out true precision tools (I love your cutting tool, but it never cuts at a 90 degree angle). I’ve adjusted my retraction settings, tried multiple types of filament, even installed a new cooling fan. Only thing I can think of is maybe it’s somehow gotten heat damaged? I’ve been super pleased with all the other products I’ve gotten from you guys, so I’m hoping maybe you guys know of something I’ve missed?

It sounds like your PTFE fitting may not be holding the tubing in place, they are parts that wear out over time. Not sure what one you are using but the stock Creality ones are known for letting go of tubing frequently. There is a mod on thingiverse from “onebadmarine” that prevents the tube from backing out even if you have an issue with the PTFE fitting. Check out the mod here: https://www.thingiverse.com/thing:3203831

This PTFE tube is far superior to the stock one on the E3 V2. My prints seem to have improved in quality. Make sure you get TH3d’s PC4-M6 fittings as they greatly decrease the play in the bowden tube as well.

I love this tubing. It works well leading up to my direct drives and excels as allowing more abrasive filaments slide without binding on my Bowden printers. Stuff takes heat like a champ inside traditional PTFE hot ends. Cut flush, and ensure your fittings are in good shape, and you should not need to tweak or maintenance too often at all.

Simple and easy upgrage to my Sunlu S8. You can definetly feel the difference when manually feeding filament thru it.
