CO2 Adapter Fit for Soda Stream Terra Water Maker Machine and Fit for Large CO2 Storage Tanks and Soda Machine Pink CO2 Cylinder System 8mm Direct Adapter Hose Gold

I have a 20lb CO2 tank and connected it to this piece with a hose I had and now have a nearly endless supply of CO2 with my SodaStream. I cannot recommend this enough.

Machining tolerances need to be pretty tight for these to seal correctly, due to the double o-ring seal that Sodastream decided to use. Unfortunately the one that I got appears to be every so slightly undersized, which means it doesn't seal and passes CO2 past the seals even when it's not being used. Over a day or two that will result in your bulk tank full of co2 being an empty tank.I can't recommend this. I'd send it back but I'm out of the return period.

It did connect to my quick coupler and it does let some Co2 through but just a little... Not enough to carbonate the bottle. I've fiddled with this thing 9 way to Sunday and still can't figure out why it won't work or what's wrong?
