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

These seem to be good replacements for the hotend of the Creality Ender 3. They are solid, made a good connection, and had some sort of tape around the threads for a better connection.

I got these to modify my Prusa MMU2S, so that I could remove the PTFE tubing from the back of it. Ive had them in for almost a year, and so far theyve held up great. No issues with pinching the tubing, poor hold, or difficulty removing the tubing.

These are not what you are looking for. These are recessed into the body giving it a shoulder for your filament to hang up on

I do not like writing reviews, but like this item

The input end of the Endor 3 takes a 4mm thread, not the 10mm thread on these.

Used to replace bowden tube holder on Creality CR10S Pro 3d printer. Direct replacement fit with no issues.

I needed to replace a slipping OEM fitting on my AnyCubic i3 Mega printer. This one worked well. Unfortunately, I really have no need for all of the extras but I understand it probably doesnt make economic sense for the seller to offer only 1 or 2 packs.

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.

Threads are enormous, not 6mm

These PTFE fittings are of good quality and work well with my HICTOP 3D-12 printer setup.
