Climate makes components for heating, cooling and refrigeration systems, including valves, heat exchangers and insulated flexible ducts.
Customers include plumbing and refrigeration wholesalers, building-material retailers, equipment manufacturers, utilities and electrical distributors. Mueller’s products are used in new homes and commercial buildings as well as in repairs and remodeling. Other applications include automotive parts, industrial machinery, telecommunications and power distribution.
The company operates in the United States and in Canada, Mexico, Great Britain, South Korea, the Middle East and China. Its chief executive officer and chairman is Gregory L. Christopher. Mueller employed approximately 4,832 people as of December 27, 2025.
How it makes money
Mueller earns money by manufacturing and selling metal products and by reselling selected plumbing products. Its three segments are organized primarily around the products they offer.
Piping Systems makes copper tube, fittings, line sets and pipe nipples. A line set connects components of an air-conditioning or refrigeration system. The segment also resells products such as steel pipe, plumbing valves, faucets and fittings. It sells to wholesalers, distributors, retailers and air-conditioning equipment manufacturers, using its own sales organization and agents.
Industrial Metals sells brass rod and shapes to manufacturers that machine them into parts. It also makes forgings, valves, specialty tube and other metal components. Its Nehring business sells wire and cable for utility, municipal, telecommunications, electrical distribution and equipment-manufacturing uses.
Climate sells components and systems used in heating, air-conditioning and refrigeration. These include refrigeration valves and fittings, high-pressure components, heat exchangers and insulated flexible ducts. Its customers are predominantly wholesalers and equipment manufacturers in the United States.
Prices for Mueller’s products are affected by supply and demand for its products and competing products. The company generally attempts to pass higher raw-material costs to customers, but increases in its costs can precede increases in its selling prices, and competitive pricing can limit its ability to raise them.
New construction drives demand for many products, while repairs and remodeling also generate demand. Sales typically moderate in the fourth quarter as construction activity slows and customers shut down for holidays, maintenance and inventory counts.
Customers and how it sells
Mueller sells through several channels, depending on the product. Piping Systems serves plumbing and refrigeration wholesalers, distributors to manufactured housing and recreational vehicle businesses, building-material retailers and air-conditioning equipment manufacturers. It markets primarily through its own sales and distribution organization, supplemented by agents.
Industrial Metals sells primarily to domestic equipment manufacturers serving industrial, construction, heating, plumbing, refrigeration, utility, telecommunications and electrical distribution markets. Its wire and cable products also serve utilities and municipalities. Climate sells predominantly to wholesalers and equipment manufacturers in the U.S. heating, air-conditioning and refrigeration markets.
Mueller has operations throughout the United States and in Canada, Mexico, Great Britain, South Korea, the Middle East and China. Its domestic piping products are made and sold in the U.S. and exported worldwide. Great Lakes makes copper tube and line sets in Canada and sells primarily in the U.S. and Canada. European Operations makes copper tube in the United Kingdom for sale throughout Europe.
The South Korean Jungwoo-Mueller joint venture makes copper joining products sold worldwide. Mueller Middle East makes copper tube for markets in the Middle East and Northern Africa.
Suppliers and costs
Metals and energy are inputs to Mueller’s manufacturing operations. The company normally obtains a substantial portion of its base metal requirements, primarily copper, through short-term contracts for refined copper and open-market purchases of scrap. It obtains other brass-making materials, including zinc, tin, lead and brass scrap, from producers, dealers and customers with process scrap. Aluminum raw materials are purchased on the open market from major producers.
Mueller’s copper tube facilities can use both refined copper and certain grades of copper scrap. The company has commitments from refined copper producers for a portion of its metal requirements for 2026. Its facilities also use natural gas, fuel oils and electricity.
Raw-material and energy costs have been volatile and affect production and distribution costs. Mueller attempts to pass cost increases to customers or adapt its activities, but may not do so fully. Tariffs can also affect the cost of products, components and raw materials.
As of December 27, 2025, approximately 1,820 employees were represented by unions. Mueller expects to renew its union contracts without material disruption, though new agreements could increase wages or benefits.

Competitive position
Mueller competes with different manufacturers in each product line. In U.S. copper tube, domestic competitors include Cerro Flow Products LLC and Cambridge-Lee Industries LLC. NIBCO, Inc. competes in domestic copper fittings. Copper tube and fittings also compete with imports and products made from other metals and plastic.
In brass rod, competitors include Wieland Chase, LLC and foreign manufacturers. In wire and cable, competitors include Prysmian S.p.A. and Southwire Company, LLC. Across its markets, Mueller faces potential pressure from imports, substitute products and changes in technology.
Mueller markets piping products through its own sales and distribution organization and through agents. It has manufacturing and sales operations across several regions, and its copper tube facilities can use either refined copper or certain grades of scrap.
Our reading: The sales network and geographic reach provide some competitive support because they help Mueller serve customers across markets. Our reading: Feedstock flexibility provides some operating support, but it does not remove exposure to metal prices or supply disruptions. Our reading: Intellectual property is a limited source of protection: the company does not materially depend on patents or other listed intellectual property, and substitutes compete with its products.

| Cambridge-Lee Industries LLC | U.S. copper tube | Medium |
| NIBCO, Inc. | Domestic copper fittings | Medium |
| Wieland Chase, LLC | Brass rod | Medium |

Growth opportunities
Mueller’s products serve new residential and commercial construction, repairs and remodeling, and industrial applications. New housing starts and commercial construction are important determinants of sales to its heating, air-conditioning, refrigeration and plumbing markets. Repairs and remodeling also drive demand for those products.
The company’s strategy for long-term growth depends in part on making acquisitions and realizing their expected benefits. It has acquired businesses in Europe, Canada, South Korea, the Middle East and the United States. Mueller expects past and future acquisitions to enhance its customer offering and improve long-term profitability, although it may not realize those expectations.
Mueller acquired Nehring on May 28, 2024. The company identifies Nehring as a platform for expansion in energy infrastructure. Nehring makes wire and cable for utility, municipal, telecommunications, electrical distribution and equipment-manufacturing markets.
Mueller also acquired Elkhart Products Corporation on August 2, 2024, complementing its Piping Systems businesses. Its existing product range reaches markets beyond construction, including automotive components, industrial machinery, compressed gas and power distribution. Climate products serve applications including geothermal systems, swimming pool heat pumps, marine equipment and heat reclamation.

Structural risks
- Metal and energy costs: Copper, brass, zinc, aluminum and energy prices have been volatile. Mueller may be unable to pass cost increases to customers quickly or fully, which could hurt operating margins. Supply interruptions could also affect manufacturing.
- Construction cycles: Housing and commercial construction demand is sensitive to economic conditions, interest rates and credit availability. Prolonged weak demand or excess supply could reduce revenue and margins.
- Competition and trade: Imports, substitute materials and new technologies can reduce demand or pressure profitability. Tariffs and other trade barriers can raise costs or affect customers’ businesses.
- Environmental and legal liabilities: Environmental remediation costs may exceed reserves, and changes in regulations or enforcement could require additional spending. Claims and regulatory proceedings can also create costs and divert management resources.
- Operational disruption: Strikes, failure to renew union agreements, severe weather or interruptions at customers and suppliers could disrupt operations. Cyber incidents could expose data or cause production downtime.
- Acquisitions: Mueller may not successfully integrate or grow acquired businesses, or realize the benefits it expects from them.
Bottom line
Our reading
Mueller is a manufacturer and distributor whose sales span construction products, industrial components and electrical infrastructure. Its business combines established routes to wholesalers and equipment manufacturers with exposure to construction cycles, metal costs and competing materials. Acquisitions add markets, but their contribution depends on integration and realizing the benefits Mueller expects.
