UNSPSC 40173603: Cast iron pipe reducing coupling

Pipe reducing coupling made of cast iron

UNSPSC 40173603 Cast iron pipe reducing coupling, a Commodity code, represents a narrow product category within water and sewer infrastructure supply chains. State and local governments procure cast iron pipe reducing couplings as discrete line items within larger water system materials contracts—notably as components in meter assemblies, bypass systems, and distribution networks. The issuing-body mix spans municipal water departments, county utilities, and special-purpose water authorities; recent opportunities show activity from city water services departments (Phoenix), county utility authorities (Jackson County), and county water resource departments (Gwinnett County) purchasing these components alongside related piping materials and fittings as part of ongoing operational supply agreements.

Geographic spread of recent activity centers on the Southeast and Southwest; opportunities posted in 2026 involve Georgia (Gwinnett County, Franklin County), Florida (Volusia County), Arizona (Phoenix), and Massachusetts (Berkshire Regional Group Purchasing Program representing 32 Berkshire County municipalities). Representative recent solicitations include the City of Phoenix Water Services Department's IFB-26-0217 for water pipe and miscellaneous fittings issued February 23, 2026, with an offer deadline of February 19, 2026, seeking 15 product groups including couplings and reducers for a five-year contract; Volusia County's ITB #26-B-42LS for Materials for Water and Sewer Operations issued March 9, 2026, specifying materials compliant with American Water Works Association standards and American-made metal components; and the Berkshire Regional Group Purchasing Program's FY27-04 Culvert Products category issued April 19, 2026, as part of a cooperative purchasing vehicle serving 32 municipalities. These opportunities typically require AWWA or ANSI/ASTM certification, firm pricing for initial contract periods, and compliance with prevailing wage or federal Davis-Bacon Act requirements when federal funding applies.
