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

JUST AS ADVERTISED THANKS

These grip the tube too hard and tend to create ridges in it that makes removal hard.

After deciding to take a chance with these since they were recommended in a Creality message board I almost instantly regretted it. I had made several flawless prints with the stock connector on my CR-10s Pro using PETG filament and then the connector broke. I then threw one of these on and set up my next print. 5 minutes into the print nothing was coming out. Naturally I thought the nozzle was clogged so I went to pull the filament out but it wouldnt budge. I unscrewed the connector amd found that the ptfe tube was sitting crooked inside the fittingand the results are shown in my picture. The filament was pinched and spooled up inside the cavity. I tried feeding the tube at different lengths through the connector and tried 4 different connectors amd they ALL had the same results, crooked tube and pinched filaments. TLDR: These connectors cause jams. I have never had anything like this happen before with the OEM connectors. These went right where they belong, the trash.

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!

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 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.

You pay for a new and get used. The connectors are not as showed in pictures.

This is EXACTLY the part that I needed for my ANET E10 3D Printer. It fit without any issues and the feeding tube is securely in place.

Theyre a snug fit for 4mm OD PTFE, perfect for dry boxes.

Much better than the factory connectors!
