UNSPSC 40172603: Cast iron pipe coupling

Pipe coupling made of cast iron

UNSPSC 40172603 Cast iron pipe coupling is a Commodity code that covers metal pipe couplings and related connection fittings used in water and sewer infrastructure projects. State and local governments buy cast iron couplings and comparable metal fittings as components within broader water distribution and sanitary sewer replacement work. The code appears in solicitations from county sanitation districts, municipal water departments, and utility authorities undertaking mainline rehabilitation, service connection work, and infrastructure upgrades. Issuing bodies include county sanitation districts, city water departments, county utility authorities, and county public works agencies—organizations managing water and wastewater systems at the local and regional level. The work tends to bundle coupling purchases with pipe, valves, and fittings into larger unit-price or annual supply contracts rather than standing alone as a discrete commodity procurement.

Recent activity clusters in California and Georgia, with solicitations posted between late April and mid-October 2026. Representative opportunities include Santa Clara County Sanitation District No. 2-3's Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026), which specified removal and replacement of vitrified clay pipe and cast iron sections totaling 1,080 linear feet of 6-inch pipe alongside service connection wyes and fittings; Pinellas County, Florida's Ridgewood Estates Sewer Improvements and 82nd Avenue & 113th Street Water Main Improvements (IFB 260652ITBC, minimum qualification due October 13, 2026), which included approximately 6,800 linear feet of 6-inch water main replacement with fire hydrant and gate valve installation; and the City of Marietta, Georgia's annual contract for water service saddles, couplings, clamps, and valves (PE77023NONST2027000000714, due September 22, 2026). A 10% SBE participation goal applied to the Pinellas County contract. Opportunities require FDOT pre-qualification, state contractor licensing, bonding, and professional references demonstrating similar-scope experience within seven years. Most projects operate on a unit-price or lump-sum basis with 65- to 380-day completion windows.
