From america’s first brass forge to a modern industrial giant.
Early Beginnings. Beginning as a pioneer in brass forging, Mueller Metals Company was founded in 1917 to meet the growing demand for munitions during WW I. The company prospered in the 1920s by developing brass forgings that would not leak, which helped spur the growth of modern refrigeration. The company also pioneered the development of copper tube for both underground and indoor plumbing and changed its name to Mueller Brass in 1927.
StreamLine® Sets a New Standard. When Mueller introduced StreamLine® solder-type copper fittings in 1930, the plumbing world changed forever. The new StreamLine soldered fittings were strong, precise and reliable, which helped establish all-copper plumbing systems as the industry standard.
Since 1930, Mueller has grown to become one of the largest suppliers of copper tube and fittings in the world, as well as a leading producer of other flow control products.
StreamTECH Raises the Bar. Mueller Industries recognized that the existing mechanical joining systems were either too expensive or cumbersome. So, in collaboration with the 3M Corporation, Mueller developed StreamTECH, a revolutionary new flameless joining system that utilizes a high-tech structural adhesive with a sophisticated engineered sealing mechanism to produce a low-cost, strong, reliable plumbing joint.
What is StreamTECH?
StreamTECH™ is the result of a strategic collaboration between Mueller Industries and the 3M Corporation to develop a flameless high-performance copper joining system that does not require the use of heavy, expensive tools or high-cost copper fittings.
development of the robust joint
Mueller's engineered seal uses a proprietary one-way lip-seal design that compensates for imperfections in the tube for a positive surface connection around the entire joint. It also forms a locking adhesive barrier which assures an even and precise dispersion of the adhesive over the surfaces of both the tube and interior of the fitting. The result is an exceptionally strong, rigid, watertight connection that provides burst pressure strength that tests higher than any other flameless joining system currently available.
