Review: Reliable, Tight Fit - 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.
