UNSPSC 40172602: Carbon steel pipe coupling

Pipe coupling made of carbon steel

UNSPSC 40172602 Carbon steel pipe coupling, a Commodity code, encompasses fittings and connectors used in water distribution and sanitary sewer infrastructure replacement projects managed by county and municipal utilities. State and local governments procure carbon steel and stainless steel couplings, saddles, clamps, and associated valve components as part of ongoing water main rehabilitation, sewer line replacement, and system extensions. The issuing bodies are primarily county sanitation districts, county utility authorities, municipal water departments, and county public works divisions; these jurisdictions source couplings and fittings both through dedicated materials contracts and as line items within larger infrastructure construction RFPs and ITBs that bundle labor, materials, and equipment.

Recent activity spans California and Georgia, with standout opportunities in Santa Clara County and Pinellas County, Florida.

The City of Marietta, Georgia solicited annual-contract bids for water service saddles, couplings, clamps, and valves (August 26, 2026; due September 22, 2026), while DeKalb County, Georgia issued a three-year multiyear ITB (July 27, 2026; due August 27, 2026) for quick insertion valves, tapping sleeves, and resilient wedge insert gate valves across pressurized and non-pressurized systems.
