Review on High-Quality Beduan Chrome Plated Brass Female Fittings: A Reliable Choice for Your Plumbing Needs by David Golden

I used this as an outlet valve for a CO2 regulator. I just couldn't glue it. No thread sealant, no teflon tape, no matter how hard I tightened it still flowed. I think this is because the valve is actually oversized and has a threaded adapter to make it smaller. Bubbles seemed to be coming from this interface (between valve and adapter) when I submerged the whole setup to check. I have no idea what mine is just bad, but that doesn't bode well for their quality.
