BIQU PC4-M10 Pneumatic Connector Fittings Bowden Tube Coupler Male Straight PTFE Tube Push for E3D-V6 Bowden Extruder 3D Printer (Pack of 10pcs)

The fittings I received are NOT the ones shown in the photos. The ones in the photos show FUSUN 4 is printed on the black release cap, but the ones I got have DONT stamped into the plastic. The DONT ones are very cheaply made and are famous for not releasing when they should and, on the extruder, often breaking and releasing filament to pile up everywhere. They will work for a while but thats all I can give them. Go for the WITBOT ones instead.

They came in as described and do their job. Several weeks in with no issues. If you install them correctly you shouldnt have any problems with the bowden tube slipping, ripping, etc. Good price and value for the product.

I have yet to encounter a connector like this where the small metal teeth internally dont break after some use. While these seem to hold up better than some, they still fail reasonably quickly. Its a good thing they come in large quantities for cheap.

Purchased this pack to replace a broken connector on my sons Creality Ender 3 Pro. This popped right in and had him back up and running within minutes. Construction seems at least as good as the original part, maybe even a bit better. And since its a large pack, we have plenty of extras if it fails in the future!

good quality, thank you
