UNSPSC 40183100: Tube fittings

UNSPSC 40183100 Tube fittings, a Class code, encompasses supply contracts for industrial piping components—metal and plastic fittings, couplings, elbows, reducers, valves, and related hardware—procured primarily by water and wastewater utilities, public works departments, and county governments to support infrastructure maintenance and capital replacement projects. State and local buyers source these materials on both as-needed and project-specific bases, often requiring compliance with American Water Works Association standards, American Iron and Steel requirements, and delivery within tight timeframes to support ongoing operations and emergency repairs.

Municipal water utilities and county utilities departments dominate the recent activity under this code. The City of Phoenix Public Works Department issued an IFB on July 8, 2026 (due August 12, 2026) for industrial pipe and miscellaneous fittings on an as-needed basis, with a three-year term and two optional one-year extensions; delivery must occur within 24 to 48 hours from purchase order, and contractors must maintain local inventory and dedicated contract representation. The City of Sarasota issued an ITB on June 29, 2026 (deadline already passed as of the current date) for materials-only bids on pipe, fittings, and appurtenances for a water main replacement project, with materials restricted to an approved list and delivery required within ninety days. The Oregon Department of Transportation solicited ductile iron pipe fittings and valves for a water main replacement project under ITB S-73000-00017088 (bids due July 13, 2026), with Buy America and Build America Act compliance required. The City of Arlington Water Utilities Department posted a solicitation on May 7, 2026 (due May 21, 2026) for an annual requirements contract covering five specifications of HDPE water pipe totaling 49,000 feet across multiple diameters. Florida and Oregon jurisdictions see the most recent activity; the code shows limited activity outside those states and Texas in the recent-opportunities block. Most issuers are cities and counties managing water, wastewater, or stormwater infrastructure; no state procurement departments or school districts appear in the recent record under this code.
