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 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.

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.

Much better than the factory connectors!

As others have noted, these are cheap. It seems about a third will not release the tubing when depressed.

The item does not match the photos. I specifically purchased these because I thought the bottom was flat, not recessed.

JUST AS ADVERTISED THANKS

Setting up 5 color 3d printing was a bit of a challenge until I saw a mod that suggested using these in place of the clamps that were specified. This was a much better option. They grasp the PTFE tubing perfectly and hold it while also allowing easy removal.

Good

Very nice Pneumatic connectors. The 4mm OD teflon tube fits very securely in them. It can be passed completely through if desired. When the spring loaded ring is released it is quite secure.

These hold as good as the originals. Just a little more play than the Capricorn branded one I just replaced. These are not reusable, once you take the tube out, they wont hold again.
