Our most popular regulator has a 0-60 PSI keg gauge, which displays dispensing pressure, and one 0-2000 PSI regulator gauge. Integral pressure relief in the regulator body, and combination shutoff/check valve on the gas line, which allows you to instantly turn off the pressure to your kegs without beer backing up into the gas line. Use a gas connector kit (KX03-KX04) to connect a soda keg. Includes a reusable nylon cylinder washer.
