Review on 🍺 HZFJ Brewing Oxygenation Kit: High-Performance Oxygen Regulator & Valve Set for Disposable Tanks, Compatible with H2O MAPP Bottles for Beer Brewing by Chris Tobin

(very loose fit on disposable red Bernzomatic O2 bottles). I finally managed to attach one, but it doesn't look like it's properly seated. Poor design: The stem that presses on the cylinder valve needle is long enough to open the cylinder valve before one of the adapter's threads is hooked. bottle thread. This means you either have to withstand the O2 pressure to try to attach the loose return threads to the bottle, or you have to open the valve during attachment (which wastes O2 and can be potentially dangerous).
