The name says it all. The Party Pig is perfect for parties, picnics, and other outings. The Party Pig holds 2 1/4 gallons of beer at one time. The Party Pig has a pressure pouch that fits inside the bottle and when activated the bottle maintains a pressure of 15-20 p.s.i. for perfect dispensing. The Party Pig can be stored in most refrigerators because the unit lays horizontal, instead of vertical like some other mini systems. The Party Pig Kit Includes: 2 1/4 gallon Party Pig bottle, Valve assembly with gasket, attachment ring with screws, Pig holding tray with Velcro support carrying strap, and two pressure pouches.
