If you ever plan on brewing larger batches of beer, I would recommend going with the 10 gallon. If you are set on the 5 gallon, then I would remove the spigot at the store and measure the size of the hole to ensure the same fittings would work. You might also need a couple extra washers, but the parts should be the same.
