CMBecker Regulators were developed by USA, German and Portuguese partners. Many of the internal parts are precision made in Germany. These are used in commercial applications in Europe and the United States. These beer regulators are assembled and tested in the United States. They can be done in many configurations and will provide years of solid service. Unlike many of the imported regulators sold in the USA these are serviceable and designed to last a lifetime. These regulators have a five year warranty, one of the best in the industry. All warranty work is done by Kegconnection, so you will receive support on this product from the place you purchased it!
