Barrel Stopper size

[terricksa]

Does anyone know what size rubber stopper replaces a wooden bung in a full size oak barrel? Thanks in advance

do you already have the barrel? measure the hole, and brewmasterswarehouse.com has the size of the rubber stoppers listed in millimeters. a hoff stevens keg is #10 and up.

My GI Barrel is a #11.
