Specialty Enterprise is a custom manufacturer started in 1959 by John B. Finn in Chicago, IL. His goal was to create a manufacturing company with a wide variety of capabilities that could provide suppliers with an assortment of quality products. Since 1959, we have produced a large range of products for several companies. For the last 30 years we have specialized in the production of high quality thermowells as well as the modification and machining of different valves. We also still continue to custom manufacture several goods as well. Now located in the Chicago suburb of Franklin Park, IL, we are still family owned and continue to be committed to providing our clients with high quality products and responsive service. So if you need something made give us a call and see what our 50 years of experience can do for you!
