UNSPSC 40173000: Pipe half couplings

UNSPSC 40173000 Pipe half couplings is a Class code that encompasses fittings and connection components used in water distribution, sewer infrastructure, and utility pipeline systems. State and local governments buy couplings, saddles, service connection fittings, and related pressure and non-pressure pipe joining components as materials for water main replacement, sewer rehabilitation, and infrastructure extension projects. Recent solicitations show these components specified across multiple project types: the Ridgewood Estates Sewer Improvements and 82nd Avenue & 113th Street Water Main Improvements projects in Pinellas County, Florida call for pipe fittings alongside main-line pipe and valve replacement; the Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 in Santa Clara County specifies 4"×6", 4"×8", and 4"×10" wyes for service connection replacement; and the City of Marietta, Georgia and County of DeKalb, Georgia are procuring water service saddles, couplings, and related valves under annual supply contracts. Issuing bodies include county utilities, special-purpose sanitation districts, city water departments, and county purchasing offices. The mix reflects both project-specific infrastructure work and ongoing annual supply agreements for maintenance and replacement inventory.

Recent activity clusters in California, Florida, and Georgia. Pinellas County, Florida (ITB 260652ITBC, due October 13, 2026 for qualification and November 5, 2026 for final bids) is bidding coordinated sewer and water main projects with an SBE participation goal of 10 percent. Sanitation District No. 2-3 in Santa Clara County (ITB ITBRDAFY270088, due September 17, 2026) is procuring pipe and fittings for sewer mainline rehabilitation across multiple diameters. The City of Marietta, Georgia (ITB PE77023NONST2027000000714, due September 22, 2026) and County of DeKalb, Georgia (ITB 2026-034-ITB, due August 27, 2026) are establishing annual supply contracts for water service components. A Jackson County Utility Authority project in Mississippi (quote request 3170036136, due July 8, 2026) specified BABA certification and RESTORE grant funding but disclosed no detailed scope. The code shows moderate recent activity concentrated in infrastructure rehabilitation and utility system renewal rather than new construction.
