Keg couplers are necessary for serving beer out of a commercial keg. There are many different styles of keg couplers to accommodate the various styles of commercial kegs, but the most common keg couplers in the US are the D-style, or D system. If you’re looking for couplers for homebrew kegs, you’ll need ball lock fittings.
