These complete tap systems include the spear (the part that screws into the keg) a tap and a gas injection system. The picnic tap comes with a manual injector as standard but can be upgraded to the regulator that comes with the steel tapping systems. All of these fit the 2L and 4L kegs, they need the custom Growler adapter to be used on our 2L insulated growler.
These complete tap systems DO NOT include a keg or growler, pictures are for illustration only.
