UNSPSC 40171700: Pipe adapters

UNSPSC 40171700 Pipe adapters is a Class code covering rigid and flexible connector fittings used in pressurized and gravity water and wastewater systems. State and local governments buy these under this code to service infrastructure rehabilitation, main replacements, and system extensions. Recent solicitations show MJS adapters (bell and spigot configurations) for water distribution networks and sanitary sewer service connection fittings (wyes in multiple diameters) for gravity sewer mainline work. Issuing bodies include county water and sanitation districts, county departments of financial services and water resources, and municipalities in unincorporated jurisdictions. The work typically flows through informal quotations (IWQ), invitation-to-bid (ITB), and request-for-bid (RFB) processes rather than formal RFPs, reflecting the commodity nature of the goods and the fixed technical specifications that govern procurement.

Activity concentrates in California and Florida. Gwinnett County, Georgia issued an IWQ on June 15, 2026 for MJS adapters (three 48" Bell X and three 48" Spigot X configurations with gaskets and diapers), FOB Destination to the Department of Water Resources facility in Lawrenceville.
