For Almost a Century
BASO & Quality
Have Remained Synonymous

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.

Orignally 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.

On August 30, 2004, the BASO gas valve and pilot burner manufacturing business was sold to BASO Gas Products LLC, a company led by
George Sopko, the Johnson Controls Watertown Plant Manager for 12 years, and H. Michael Hein, a former Johnson Controls Financial Controller.

Today, the locally-owned BASO continues with the same employees at the same manufacturing facility. This means customers can continue to obtain the same BASO products, manufactured and supported by the same people, with the same dedication to quality.

While many things have changed in the last 95 plus years, our commitment to producing superior products, providing exceptional customer service and operating with integrity remain unchanged.

BASO Gas Products LLC...firing you up since 1914.
