Since its inception in 1914, BASO has been recognized as an innovative leader in developing and manufacturing a wide range of quality gas control products and accessories.
Originally called Milwaukee Gas Specialty Company, the facility produced gas range accessories and later added products for water heaters and furnaces.
When the company was granted an exclusive license to manufacture and market the Baltimore Automatic Shut-Off (BASO) switch in 1934, Milwaukee Gas Specialty Company and BASO quickly became synonymous. The company’s name was officially changed to BASO, Inc. in 1957.
In 1961, BASO merged with Penn Controls, and the combined entity was later purchased by Johnson Controls, Inc. in 1968.
BASO Gas Products LLC, was formed on August 30 2004, when Johnson Controls sold its BASO Gas Valve and Pilot Burner business in Watertown, Wisconsin, to
George Sopko. The vision to "go it alone" and purchase this business was the strong belief that success lies with a dedicated team of people focused on the customer and product quality, while operating in an environment using World Class Manufacturing methods and practices.
As of July 21, 2017, BASO has moved into their newly constructed 75,000 square foot manufacturing facility. This will accommodate our continued growth and insure we continue to manufacture our products to the highest quality standards and continue to provide the shortest possible lead times to our customers.
While many things have changed in the last 100 plus years, our commitment to producing superior products, providing exceptional customer service and operating with integrity remains unchanged.
BASO Gas Products LLC….firing you up since 1914.
