Connecticut was once home to some of America’s largest manufacturers, such as General Electric (GE), American Standard, Westinghouse, Pratt & Whitney, United Technologies, and Honeywell International. Today, however, these companies have left the state and it is primarily a service sector economy. However, there are still several great manufacturers around the state keeping the tradition alive and producing great products. Below are all the companies in our directory that are made in Connecticut. If you know of any more companies to add, send us a note and we’ll certify them before listing.
