I didn't know I needed this until I NEEDED it! The package arrived a day early, the parts fit my Longer 3D printer perfectly, and I had it running again in about 15 minutes!

First off, I haven't used the tube, so I can't really comment on that. I haven't seen any reason to replace my stock bowden tube, so these are just spares if I need it in the future. The couplings, however, are great. I haven't had them very long, so we'll see how they hold up over time. But I saw an immediate improvement to the consistency of my models after swapping out the stock coupling on my ender 3. I've been running the printer almost 24/7 for several days, and there's no sign of any issues yet. Even I do end up needing to replace it again in a few weeks, this barely cost me anything and there's still 3 more sets of spare couplings.

I purchased this set on a recommendation from a YouTuber who was discussing cleaning out hot end clogs and trouble shooting issues with the fittings. The bowden tube and hot-end quick fitting work great on my Ender-3 3D printer. I've actually found this tubing much easier to push into the hot end than the expensive Capricorn tubing people rave about, and the quick fitting for the hot end heat sink has been rock solid. I haven't used the blue-capped quick fitting, but the larger threaded black-capped fitting is a perfect replacement for the stock fitting. There's plenty of tubing in the package for at least 4 Ender-3 printers - maybe more.

I bought this more than a year ago. The PTFE works fine with the stock fittings (crap) and with the slightly better fittings in this kit. Unfortunately, a year later, I've upgraded to an EZR extruder to replace the stock one. This PTFE is too large to fit. Most other PTFE I have is 3.97mm OD. This stuff is 4.15mm OD, the same as Capricorn, and it will not fit in the special fitting on the EZR extruder. Another reviewer described it as "chubby" and his measurements (4.15mm) agree with mine. It works fine on stock-type fittings, but may not fit some of the specialty extruders like the EZR.

I used it for upgrading my Creality 3 Pro. It works just like it's supposed to.

My stocked ender 3 pro tube holder failed on me within the first week of having it, bought theses as a replacement. Been printing on them for a few months and they hold ip great. Haven’t used the tubes yet as I haven’t needed to replace them yet but it’s great to have them as a upgrade.

Okay. Small backstory. So I recently purchased an Anet E10 3d Printer and one day after a failed print 47 hours deep. I decided to perform some maintenance. Some where along the process, I accidentally damaged the Pneumatic Fitting that connects to the heat sink... Don't ask. Any who, I decided to purchase the set in an effort to get back on task printing 3d prints. I was able to get them today and replace the one I damaged. It fits like a glove and I have no issues what so ever. I'm glad I took time out to buy this. If you are ever in need of a replacement be it through wear and tear or by accidentally damage the part... Like I did... Purchase the item to save you some cash from buying them separately.
