HISTORY

1954

COMPANY FOUNDED IN MILWAUKEE

George Henry Baumann founds Great Lakes Rubber and Supply (GLR) under the belief that products like o-rings, hose, belting, gaskets and the newly invented PTFE (DuPont Teflon) would increase in demand during the post-World War II boom. He starts the business in November with one other employee in a 500-square-feet location at 735 N. Jackson St. in downtown Milwaukee.

RAPID ExPANSION

Under George’s leadership, the company relocates to 3118 N. Teutonia Ave. in Milwaukee, doubling the size of its facility. Around the same time, GLR partners with Parker Hannifin to become an authorized distributor of its o-rings, seals, hose and fittings product lines. This relationship with both Parker’s EMG and FCG divisions would continue to grow for the next 60+ years.

RELOCATION AND FURTHER EXPANSION

To meet a growing customer base and product line, GLR relocates to its current Milwaukee headquarters at 6150 N. Flint Rd., expanding its facility to 25,000-square-feet. The expansion allows GLR to invest in gasket manufacturing and hydraulic assembly equipment.
