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

I ordered 10 new Push 3D-V6 Fitting Connector but I only received 7. Of the 7 Connectors, each has Teflon on them (not as advertised), and the Teflon appears to have thread damage.

Good quality, as expected. Use as spare so in storage for now.

Bought these to replace the ones that came with my 3D printer and they work great very good quality and well-made. I obviously only needed to so there are many here to replace others in case I need to on Down the Line but the two I used are working great for the time being.

I do not like writing reviews, but like this item

Used them on a 3D printer. Work as intended.

Purchased to replace improper functioning Creality CR-10S hot/cool end unit. None of these would release Bowden tube either! New Bowden tubes, same results. These were to blame due to poor removability of Bowden tubes.

Exactly what I needed and works great!

They work well, price is too high imo, but they are quality

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.

Used for 3D printer bowden extension (anet a8 and FLsun Plus). That is really, what I expected. Very fast shipping with Amazon Prime.
