UNSPSC 40183105: Tube nipple

UNSPSC 40183105 Tube nipple is a Commodity code that classifies small-diameter threaded pipe connectors—particularly ductile iron, galvanized, and coated nipples with flanged or threaded connections—that state and local water utilities, public works departments, and transit authorities procure as inventory stock for routine system maintenance, repairs, and capital projects. Recent solicitations show water utilities buying these components as part of broader water main replacement and pipe fitting supply contracts rather than as standalone items; the code appears in procurement activity dominated by Florida municipalities and Georgia counties purchasing water system components on as-needed or project-specific bases.

Water utilities in Florida and Georgia drive recent activity under this code. The Gwinnett County Department of Water Resources (Georgia) issued an Informal Written Quotation in April 2026 for ductile iron pipe nipples with polyethylene DIP coating in 3-, 4-, 6-, and 8-inch sizes with flange connections and 3-foot lengths, with quotes due April 23, 2026. The City of Phoenix Public Works Department (Arizona) solicited industrial pipe, miscellaneous fittings, and equipment under IFB 26-SW-0379, with offers due August 12, 2026, covering a three-year term commencing December 1, 2026, requiring 24- to 48-hour delivery and local inventory maintenance. The City of Sarasota (Florida) requested materials-only bids for water main replacement supplies under ITB #26-31JS, requiring conformance to the City's Potable Water Approved Material List and delivery within ninety calendar days. Orange County, Florida issued a five-year sewer pipes and fittings contract (Y26-126) with an estimated five-year spending total of $28.7 million and delivery requirements including standard delivery within two calendar days and emergency delivery within four hours. Geographic activity concentrates in Florida (Orange County, City of Sarasota, City of Palm Bay) and Georgia (Gwinnett County, City of Calhoun, City of Lavonia), with secondary activity in Arizona and California. The code sees steady but fragmented demand across municipal water utilities and public works departments on multi-year or as-needed supply agreements.
