SIQUK 2 Pcs PTFE Teflon Tube (2M) 4 Pcs PC4-M6 Quick Fitting 4 Pcs PC4-M10 Straight Pneumatic Fitting Push to Connect for 3D Printer 1.75mm Filament

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!

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

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 bought this at the suggestion of lots of people on YouTube and Facebook to replace the stock, faulty couplings that ship on the Ender3 and Ender3 Pro. I ended up using the second set on my Anycubic i3 MEGA as well. Both sets are performing very well with no issues at all. I didn't use the PTFE that is included, because I prefer Capricorn tubing. The price is worth it even though you don't use the tubing, though. Will purchase again for future printers.

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.

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.

I've swapped out the stock fittings for these, and glad I did. They tube is not easily unseated and you have to give them a solid push to release the tube. The tube is also good quality.

I was watching a You-Tube video on extruder issue and the presenter recommend this product. I have used the tubing work perfectly and fittings are much better that what came on my Ender 3D Pro printer . I wish they would include the blue clip used on fitting so tube will stay put
