Schroeder America soda guns are designed to provide the performance and durability to keep drinks flowing. They are also engineered for easy servicing with easy access flow control adjustment screws, positive shut offs with no tools required, and larger fittings and barrier tubing that will not restrict fluid channels. In addition the guns feature an embedded stainless steel collar to prevent sheathing separation, a two piece heal plate, and extended life double o-rings to prevent leaks.
