Nitrogen tank / beer gas on a CO2 regulator

Postby thippe » Mon Aug 17, 2015 2:24 pm

I have my new beer gas tank for my stout hooked up with a C02 regulator and adapter.
it seems the beer gas does not register accurately on the gauge that tells me how much is left in the tank (or if it does, i have a serious leak or it takes A LOT of gas for a pour).
has anyone else noticed this or do i have a problem?

thanks

I don't have/don't use beer gas but I suspect you have a problem. It shouldn't take any more gas to push your beer with beer gas than it would on pure CO2. I would check for leaks. I would also look to weigh the tank since in my experience the tank pressure gauge can vary widely based on the temperature it's kept at.

decided to redo the gas connection going to the coupler. I was using a 1/4" flare on each side with one of those nylon washers in between -- hooked up to a micromatic guinness coupler. first time trying those nylon washers out (usually i use teflon tape)
i could not get the first nylon washer out, looks like they get crushed and molded into there, makes sense. tried to a new nylon washer, probably a bad idea and that just destroyed the 1/4" flare that was on the gas line, it pushed the metal barb all the way out.
i just attached a regular gas barb now, hopefully that works but i would still like to use 1/4" flares in the future because i'll be connecting mostly homebrew with a few guinness kegs in between.

Even though you do a good job describing it - I'm having a difficult time picturing it. Throw a little soapy water into a spray bottle and check for leaks.

The nylon washers to connect to the tank should be all you need for a seal on the coupler to the tank.

Thanks - that makes way more sense to me now. For some reason I was thinking of the connections of the regulator to the tank (which also uses a nylon washer). Would still simply advise you to hook everything up and then use some soapy water to see if you have any leaks and tighten/replace connections as necessary. Shouldn't take any more "beer gas" to carbonate and push a beer than it takes straight CO2.
