Through internal growth and acquisition Mueller has become one of the largest producers of copper tube in the world and is the only U.S. copper tube manufacturer that also makes copper fittings. Mueller has been able to increase copper tube manufacturing capability by rationalizing production between its major U.S. plants.

Mueller has invested millions to improve and expand its copper tube manufacturing capability. These investments improved all major manufacturing processes including casting extrusion, drawing and finishing. We are dedicated to being one of the most efficient tube mills ensuring reliable supply of the broadest possible product line for our customers.

Mueller established an unparalleled reputation in the refrigeration market with dehydrated and nitrogen purged and sealed service tube. The Nitrogenized^® process patented by Mueller reduces oxidation to an absolute minimum in hard length tube and is clearly the preference of contractors.
