UNSPSC 40183107: Tube coupling

UNSPSC 40183107 Tube coupling, a Commodity code, captures industrial pipe fittings and coupling devices that state and local governments procure for water infrastructure, stormwater management, and municipal utility systems. Recent solicitations show state and local buyers purchasing tube couplings and related fittings as line items within broader water main replacement, pipe rehabilitation, and outfall restoration projects—rarely as standalone commodities, but consistently as essential components of larger piping systems.

Cities of Phoenix, Sarasota, Palm Bay, and Calhoun, and Orange County, Florida dominate recent activity; Gwinnett County, Georgia and Santa Clara County, California also appear.
