BIQU PC4-M10 Pneumatic Connector Fittings Bowden Tube Coupler Male Straight PTFE Tube Push for E3D-V6 Bowden Extruder Compatible with Ender-3 Ender-3 V2 3D Printers (Pack of 10pcs)

These BIQU PC4-M10 connectors are exactly what I need to my filament containers. They hold the PTFE tube firmly, install easily, and stay put during long prints. No more wobbly or loose fittings. The only thing I can see is the thread part of the connector seem to be smaller than other connectors. Not by much but might make a difference. Solid quality and a great price for a 10-pack. Would definitely buy again.

Fits and works great

great for building a split tool for my 3d print

Worked great for me. I printed a y splitter to add an external spool to my A1 and so far have had no problem with feeding through or disconnecting tubing.

If you are in need for these, (and those with projects where they are needed, you'll know) then these are decent and will work. I've used them in dry box projects, and these worked just fine.

Excellent quality. I've used all of them without issue. Locks in the ptfe tube nicely and easy to remove.

I needed these for a y-splitter to run 2 external spools to my Bambu A1 w/AMS Lite so that I could have 6 spools hooked up at all time. They worked beautifully. I couldn't be happier with them. And I will definitely be going straight for these when I have projects that require them in the future.

Mine has survived at least 200 coupling and decoupling events with my ever changing maze of tubes. Always works great with zero debris buildup

I had broken tabs on my original fitting. These fittings are cheap and did the job as replacements. My PTFE tube is now secure.

These work fine with my BBl X1C

Does the job allowing PTFE tube through it for my filament dry boxes. Would buy again.

My stock one didn't work, the PTFE tube kept falling out, but this one has been working fine.

Exactly.As described very easy to install seam to function perfectly very happy
