Our history began with Armin Kuhlman, a second-generation German immigrant, whose first business was creating Bowls-O-Beauty (Roses encased in glass) in Melrose Park, IL. In 1956 he became friends with a local manufacturer of aluminum gas lines and had the opportunity to sell them. A year later DuPage Industries was formed and the rest is history.

Today, 63 years later, we continue Armin's vision and we are proud to still be family owned and operated, going on the third generation of Kuhlman's. In this time we have grown from our humble beginnings and now boast a product catalog with over 1400 items. We are one of the nation's largest full-line suppliers of appliance installation materials, including stainless steel gas range and dryer connectors, range and dryer electrical cords, washing machine and dishwasher hoses, and everything in between. 
Since the beginning, our mission has been to offer great customer service and competitive prices to our customers. We take pride in helping customers have access to quality installation parts at great prices so that their own businesses can thrive.  
Today, we are located in Addison, IL, less than 30 minutes from O'Hare International airport. We are able to get packages out to most customers in 4 days or less, depending on location. On top of this, orders are almost always shipped within 48 hours of receiving them, with a majority of them shipping the same day. 
We promise to always try to improve and meet the needs of our customers in an ever-changing industry, and we humbly ask for the opportunity to earn your business in which we know that you will not be disappointed. We look forward to the chance to do business with you, to grow, and succeed together.
