🔧 Joywayus Oxygen Regulator Disposable Fitting: Optimal Efficiency for Contamination-free Gas Control Review

Suitable for 1.4 oz disposable reverse thread oxygen cylinders such as Bernzomatic. As far as I can tell there are no leaks at the regulator or the thread (seal).

I ordered this item and it was supposed to have arrived in a few days, but when I opened the package the item did not look like the photos or the description. I then sent it back and asked for another one to make sure it wasn't a mistake. A few days later a package arrived with the same thing as the first!

Threading and machining is satisfactory but I was expecting something more accurate for the money. This valve flows down. I guess from now on I'll just be looking for old medical O2 tanks. If you have a really low O2 supply it might be worth considering another option. This valve assembly works, but at the end of the day it should definitely come loose. I placed the balloon over the valve and reservoir overnight, at about 250m above sea level I lost about 6 liters of O2 with the valve tightly…
