What Cerro Brass does
Cerro Flow Products LLC is a St. Louis, Missouri-based manufacturer of copper tubing, insulated linesets, and press-fit fittings serving plumbing, HVAC/R, and industrial OEM markets. The company's lineage traces to 1908 as a scrap iron dealer, with copper refining beginning in the 1920s and the first copper tube mill constructed in 1939. It operates as a wholly-owned subsidiary of Marmon Holdings, Inc., which has held the business since 1975; Marmon itself has been majority-owned by Berkshire Hathaway Inc. since 2008.
The product portfolio is organized across five lines: Copper Tubing for residential, commercial, institutional plumbing and refrigeration; CerroSet insulated Linesets for HVAC installations in Elastomeric and Black Shield variants; Industrial Tubing comprising Level Wound Coil, Continuous Coil, Cerro Groove internally rifled tube, and Exact Straight Lengths; CopperBOSS, a long-length Type K copper coil system with jobsite dispensing engineered for lead service line replacement; and CerroPress fittings, which deliver 99.9% pure copper press-fit connections. Manufacturing runs across five facilities in Missouri and Illinois, anchored by a continuous billet casting operation in Mexico, Missouri — one of a small number of such facilities in the United States and a key element of vertical integration into raw material conversion.
Cerro sells through a wholesale distribution model, with no public consumer-facing pricing; distributor price lists govern downstream transactions to contractors, engineers, and building owners. Differentiation is anchored on domestic production, BABAA compliance positioning for federal infrastructure procurement, NSF/ANSI certifications covering drinking water applications, and a multi-decade Made in USA manufacturing heritage.
