Great Lakes Rubber celebrates its 40th year of rubber manufacturing excellence

Since its beginnings in 1979 and its incorporation with Mac Valves in 1989, Great Lakes Rubber has taken care of hundreds of customers who rely on their rubber products around the world. From rubber seals holding up in the frigid climate of Alaska to a seat bumper on a Maserati, GLR products are everywhere. While the bread and butter of the company has been mastering the rubber components of a Mac Valve, what is learned there is applied to solutions for other applications.
