So I ride bikes, and have several CO2 inflators that fit over a shrader valve to inflate a bike tire. I'm wondering if these CO2 chargers they sell in homebrew shops have the same size and thread fittings that the bike inflators do, or if the homebrew style inflators have some sort of adapter that's different from a bike/car type valve stem. Can anyone confirm? I just don't want to buy one for 20 or 30 bucks if I've already got one that will work. But my current corny keg taps don't have threaded fittings to just check it myself unfortunately. I'll have to pick one of those taps up later.
