Replaced my fittings on my Ender-3 and it works better than new, along with some Capricorn PTFE tubing. Smooth sliding and fit well! I've been printing non-stop for about 6 months now, and had a jam, so I figured to replace these (after some video suggestions) while cleaning out the hot-end. Great fix for a low price (especially per connector)!

Worked on ender 3. Much tighter than stock fittings. It would be nice if you could buy less of them at once but i wont need to buy more for a long time

Used these for the bowden tube on my Ender 3. Worked perfect. Nice and tight.

I have used only one pair in a ender 3 3d printer, and it works fine so far, better than the ender 3 originals.

Worked great for my needs! Used the M6 to replace a failed bowden tube fitting and the M10 for a sealed container setup for the filament.

These couplers are really great. They have thread locker on them already AND a rubber sealing washer in the outside threads. On the inside of the coupler there are actual metal teeth that grab the Bowden Tube. This is exactly what you want. There is no slipping of the tube with these.

These were much better than the stock ones that came on my Creality printer.

I have an Ender 3. I replaced the stock fittings since they are not easy to use when adjusting the tubing. I also updated to Capricorn tube and these work great with it. They fit perfectly and compress easily to slide the tube through it.

Cumple con mis expectativas y a buen precio, para tener repuestos a la mano cuando se requieran.
