Our Story
In 1955, Harrison Browning founded Arizona Gear and Manufacturing, which was the first company to design breather valves for Hughes Aircraft missile containers. Following this success, in 1970, Roger and Joyce Stewart bought a branch of Arizona Gear that eventually turned into AGM Container Controls. Thanks to the Stewarts’ vision, AGM has become a growing family of brands delivering a wide range of products and solutions for the Aerospace, Defense, Manufacturing and Accessibility markets.
Our Values
AGM is the subject matter expert on protecting contained environments. Diligently maintaining a robust, AS9100-certified quality system, our AGM employee-owners strive for exceptional product quality and on-time delivery performance. In addition, our AGM design engineers work directly with our customers to specify products that might best suit their given application.
Headquartered in Tucson, AGM supports numerous charities and events throughout the year. In 2009, AGM was recognized with the national U.S. Chamber of Commerce’s “America’s Best Small Business of the Year” award.
