What Cerro does

Cerro Flow Products LLC is a U.S. manufacturer of copper tube, fittings, and flow control products serving plumbing, HVAC/R, and industrial OEM markets. Founded in 1908 (originally as a scrap iron dealer) and headquartered in Sauget, Illinois, the company operates five manufacturing facilities across Illinois and Missouri, including one of the few continuous billet casting facilities in the United States. Cerro's product portfolio spans CerroTube copper water tube (Types K, L, M, DWV), CerroPure medical gas tubing (ASTM B819 compliant), CerroSet insulated linesets for HVAC, CerroPress flame-free press fittings, Cerro Groove internally grooved tube for enhanced heat transfer, and the CopperBOSS bulk tube payoff system targeting lead service line replacement projects. The company holds extensive ASTM, NSF/ANSI, ASME, and BABAA certifications.

Cerro sells exclusively through a network of stocking wholesale distributors throughout the United States, targeting plumbing and HVAC contractors, industrial OEMs, engineers, and — via CopperBOSS — municipalities and utilities undertaking lead service line replacement. Pricing is quote-based and negotiated through distributor channels rather than published. The company is privately held as a subsidiary of Marmon Holdings, Inc., itself controlled by Berkshire Hathaway since 2008. Cerro operates with relative independence under Marmon's decentralized structure, with Buddy Dailey serving as President. Marketing is heavily event-driven, with active participation in AHR Expo, HARDI, MCAA, ASPE, and ServiceTitan events, supplemented by industry association memberships (ASA, MCAA, ASPE). The company is currently undergoing a brand refresh (February 2026) and recently launched CopperBOSS (June 2026) to address the federally funded lead service line replacement market.
