About Anderson Fittings
In 1947, Robert Anderson started machining fittings in a garage on the Southside of Chicago, IL. His business philosophy was simple and sound … employ good people to manufacture a quality product with excellent service and the customers will reward the effort with their business.
HE WAS RIGHT!
Today, Anderson Fittings is one of the largest and most trusted domestic manufacturers of brass fittings. A lot has changed in our 60 YEAR history. We’ve moved out of that garage and into two manufacturing facilities.

Talented People… Quality Solutions… Exceptional Value
Oak Forest, IL is our flagship plant and serves as business headquarters. This 85,000 square ft. facility produces the majority of the products in our brass catalog offering. Additionally, engineering, customer service, sales, marketing, quality assurance and finance functions are based here. Oak Forest received ISO 9001 certification in 1994. Each year, Oak Forest converts thousands of tons of brass raw material into both straight and shaped fittings.
Frankfort, IL is home to our brass OEM plant. This facility is committed to manufacturing brass fittings and components to specific customer specifications. Frankfort is ISO 9001 certified and houses both high volume and short-run manufacturing expertise. Also, the Frankfort team specializes in machining many different brass alloys including standard CA360, Red Brass, PbF (Lead Free) Brass, DZR and others.
