Ewigkeit PTFE Teflon Tube with PC4-M6 Pneumatic Fitting and PC4-M10 Straight Quick in Fitting for 3D Printer 1.75mm Filament(Pack of 9cs)

I made a mistake. I broke one of the connectors and needed a replacement. Shipping was fast, quality was impeccable, price was worth it. Thank you so much! I made my repair with these parts and everything works as expected!

I purchased these because my tube kept coming out on the extruder end. After replacing the fitting, they held properly. These were much tighter of a hold than the stock fittings on both of my printers. No more issues and great price.

First replacement Bowden tubes I've ever ordered so I can't compare it to others, but they worked very smoothly and fixed the only real problem people are having with their CR-10 Mini's which was the factory fittings were weak.I plan on using it on a scratch build I'm doing too and have confidence in the quality in general.But if you're reading reviews looking for something to fix the Mini's problems, ya just found the right product.

Fittings are much easier to work with. Can pull the ptfe tube out of them much easier and, the bite they have on the tube makes them secure so they don't move around durong printing. One issue I did have though was that the tube came with a few dents in them. They were still useable after cutting to a certain length but dents can make it difficult to flow so I had to remove a star

For my scenario I really didn't know whether the M6 or M10 fittings would be better so this option with a sampling of both along with the PTFE tubing was perfect! Would be nice to have a bit more length to the tubing... but for a proof-of-concept this was exactly what I needed and solid quality as well. Would definitely buy again if/when the need arrises.

Perfect replacement tubing for my CR-10! I was originally using the stock tubing that came with it, but after a clog that just wouldn't come out I decided to try out some Capricorn XS tubing, which wasn't working too well at all for some reason.I then decided to buy this and voila! Prints like a dream now. The included couplers are also much nicer than the ones that came stock with my CR-10, and the tubing itself is quite slippery and seems to be working very well so far.

From stock push-connector which wouldn't hold no matter what, to these which won't release no matter what. They're great until you need to get the tube out, and then a whole lot of effort doesn't go far. These things just would not release. Had to cut the tube and unscrew them. Replaced them with the other two in the package and ended up with the same problem. It may be due to the Capricorn tubing? I can't say with certainty as I didn't try them with anything else.

Virgin connector broken, and I found this at the suggestion of lots of people on YouTube and Facebook to replace the stock. using on my Anycubic i3 MEGA, the sets will last for years. Both sets are performing very well with no issues at all.
