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

Designed a new box for printer filament, and they worked great

All is OK

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.

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

Items received did not have beveled edge as shown in the product description, instead have a hard edge which makes it difficult to start filament through when fitting is screwed in to mounting. Specifically ordered this product over other brands because of the beveled edge and did not get the product advertised.

Quality connectors for my E3D bowden system.

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.

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

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

very good quality. good clamping
