UNSPSC 40173606: Malleable iron pipe reducing coupling

Pipe reducing coupling made of malleable iron

UNSPSC 40173606 Malleable iron pipe reducing coupling is a Commodity code representing small-diameter metal pipe fittings and connectors used in water, sewer, and utility infrastructure systems. State and local governments procure these components as part of broader water and wastewater operations, repair, and capital improvement work. The recent opportunities show malleable iron reducing couplings and related metal fittings appearing alongside stainless steel bypass spools, ductile iron flanged fittings, gate valves, corporation stops, and meter stops in multi-line-item solicitations from water utilities and county infrastructure departments. Issuing bodies span municipal water departments (City of Phoenix), county water and sewer authorities (Volusia County, Gwinnett County), and regional utility districts (Jackson County Utility Authority). These buyers treat reducing couplings as commodity materials supplied on an as-needed basis under long-term agreements rather than as standalone procurements.

Recent activity concentrates in the South, with Georgia (Franklin County, Gwinnett County) and Florida (Volusia County) showing active water infrastructure spending, and Arizona (City of Phoenix) issuing multi-line-item water pipe and fittings contracts. The City of Phoenix Water Services Department posted an Invitation for Bid on February 23, 2026, for water pipe and miscellaneous fittings (IFB-26-0217) with a five-year term commencing May 1, 2026, covering 15 product groups including couplings and reducers, with sealed offers due February 19, 2026. Volusia County solicited competitive sealed bids for Materials for Water and Sewer Operations (ITB 26-B-42LS) with responses due February 4, 2026, covering stainless steel repair clamps, gate valves, fire hydrants, backflow preventers, and related piping components. The Jackson County Utility Authority requested written quotes for materials for the South Central Septic Abatement Project with BABA certification required and a quote deadline of July 8, 2026. All materials must meet AWWA and ASTM standards, and contracts typically carry three- to five-year terms with firm pricing for initial periods and annual redetermination provisions thereafter.
