When Eric Edelmann founded the automotive products company that bears his name in Chicago in 1909, his product line consisted of a battery tester and push-pull control cables. Some years later he began manufacturing anti-freeze testers, automotive brass fittings and general products.

In 1959, E. Edelmann & Co. began distributing a line of power steering hose, and in 1960 took over production of the hose. The company initially manufactured power steering hose for 25 vehicles.
