Regulator Question

[sweet_corn]

I ordered a cornelius co2 regulator off of ebay. It was lost in shipping. The seller sent a replacement, but said it is an argon/co2 regulator. Will that work for my draft system?

should be just fine, I mean all your regulating is the amount of pressure to your keg. I usually have it at 12lbs so if it reads that low I wouldn't see a problem
