UNSPSC 40173603: Cast iron pipe reducing coupling

Pipe reducing coupling made of cast iron

UNSPSC 40173603 Cast iron pipe reducing coupling is a Commodity code under which state and local governments procure water and sewer infrastructure repair materials, including reducing couplings and related pipe fittings for main line replacement, extensions, and rehabilitation work. Recent opportunities show municipalities and special districts sourcing cast iron and other metallic pipe couplings as components of larger water main and sewer line projects involving removal and replacement of aging infrastructure. The issuing bodies include county utilities, sanitation districts, and municipal water departments managing distribution and collection systems across their service territories.

Recent activity concentrates in California and Florida. Pinellas County, Florida posted an ITB (Solicitation 260652ITBC, due October 13, 2026 for qualification and November 5, 2026 for final bids) for coordinated sewer improvements and water main replacements involving approximately 6,800 linear feet of 6-inch water main and 500 linear feet of 12-inch sanitary sewer pipe with associated fittings and couplings across two project IDs in the City of Seminole. Santa Clara County, California's Sanitation District No. 2-3 posted an ITB (ITBRDAFY270088, due September 17, 2026) for structural defect repairs including pipe bursting and VCP replacement with PVC and HDPE at multiple diameters plus service connection fittings across thirty-five point repairs and five mainline replacements in the eastern foothills. Georgia cities including Marietta and DeKalb County have solicited water service components including couplings and valves on annual and three-year multiyear contracts (PE77023NONST2027000000714 and 2026-034-ITB due September 22 and August 27, 2026 respectively). The work typically falls within larger capital projects with completion windows of 60 to 380 calendar or working days and standard bonding and performance requirements.
