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

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

Not what the picture shows in the listing, these have a large gap inner diameter allowing the PTFE tube to move around. Do not buy!

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

1 broke within 2 weeks of use. Guess for the price this is ok.

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.

I ordered these because I needed them quickly. I was a little concerned about the quality because of the really low price compared to my normal source. I didn’t need to be concerned. These are very nicely made and every bit as good as my normal source. I may continue to use my normal source out of loyalty since they have provided me with other services as well as parts, but in a pinch I won’t hesitate to buy these again.

I used these to replace Crealitys cheap fitting on my Ender3. I dont have any issue with the bowden tube coming out of the hot end. Now its time to replace the one on the extruder. That said this is the fitting for the hot end and will not fit on the extruder.

Someone told me to buy this for my monoprice voxel printer and it was not the correct kind. Had to send back.

does what it is sold for

One of those things you go through, especially if your new to 3D printing which I am.
