The stainless steel dual ball spray gun is the only option you need for home brewing and forced carbonation. Beautifully constructed and perfect for our little beer kegs. Connect your gas and your liquid disconnector to the ball lance and you're done. Pressure releases automatically at 35 psi (if using the red PRV) or 70 psi and is standard on our small mini barrel kits. It features silicone tubing which is more flexible and heavier than beer, meaning you can dispense kegs sideways and still have a beer pick-up tube at the bottom. The tapping head is fully removable for cleaning and maintenance. All parts are standard including the ball lock lever, o-rings and even the pressure relief valve. Suitable for all mini drums with M 33 x 1.5-55 thread. Thread size: M 33 x 1.5-55
