Sioux Chief got its start packaging specialty fasteners and other items geared toward residential plumbing jobs. In the early 60s, Ed borrowed the idea of spinning copper tube closed for simple air chambers and adapted it for stub outs which could be used by plumbers. This preformed copper tube saved plumbers from sweat soldering tube caps onto their copper tube for water shock and test-off purposes. By 1975 a heavy emphasis on sales and new product development began when Ed's two eldest sons purchased the corporation and took over operations. Since then Sioux Chief has welcomed the third generation of family members to the team and has introduced a wide range of innovative products.
