Maybe. You need an airtight seal with the bung and carboy neck. You may try placing bung inside a piece of plastic wrap that you pull tight as you seat it, or food grade petroleum or glycerin will usually do the trick. If it is one of the rubber/silicone bungs placing it in heated water for a few minutes does wonders.
