Eric Edelmann started Edelmann (now Plews & Edelmann), in 1909, when his entire product line was made up of a battery tester and push-pull control cables. After a few years he began making anti-freeze testers, automotive brass fittings and general products. Edelmann began distributing a selection of power steering hoses in 1959 and in 1960 took over the production of the hoses. The company started out manufacturing power steering hoses for 25 vehicles - now the Edelmann catalog is made up of over 1,800 part numbers. Edelmann now provides the automotive industry with over 3,500 selections of power steering hose and brass and plastic fittings from their cutting-edge facility in Dixon, Illinois. Edelmann supplies a large variety of products that involve specialized manufacturing processes. They make products engineered selectively for their customers' specialized needs.
