Product Description

Mueller Industries, historically headquartered in the American Midwest with major copper fabrication and refrigeration-fitting plants across the U.S., is publicly identified in asbestos litigation as a leading supplier of copper and brass pipe fittings for refrigeration, HVAC, and plumbing service.
