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.

The 1970’s brought the addition of the Plews division and their lube equipment and air line products to the Edelmann family. Plews Manufacturing and Sales Corporation was originally founded by R.G. Plews in 1927. At that time, the railroad industry was the primary focus for the company’s extensive line of oil cans. As the transportation industry went from trains to passenger cars and trucks, Plews shifted their focus to developing the tools necessary to service this new mode of transportation. During the 1960’s and 1970’s, other products in the lubrication field were added including funnels, measures, grease guns and other service-related items. E. Edelmann & Co. officially changed their name to Plews/Edelmann in 1995.
