This is very similar to our regular Weldless Ball Valve but specifically designed for use on mash tun coolers. The longer bulkhead allows the ball valve to open full swing on applications where the cooler spigot is indented. It includes the 1/2" full port ball valve, barb, bulkhead fitting, high temp washers and SS washers. The bulkhead accepts a 1/2" NPT male fitting. This allows you to easily connect to a false bottom using a barb and hose, or other 1/2" connection as needed. Simply remove the old cooler spigot and install this one in its place.
