While doing some research, I came across this:
"When youre working with a Hoff Stevens Keg, parts like this wooden bung are important. Designed specifically for plugging the bunghole, this valuable piece of hardwood fits nice and snug to prevent leakage.
NOTE: We feel obligated to mention the level of maturity required to use the term bunghole appropriately. Its not easy and were actually pretty surprised that we managed to make it through this entire description without a single tasteless comment. Thank you for your support."
