UNSPSC 40183103: Tube union

UNSPSC 40183103 Tube union (Commodity) represents a narrow product category that state and local governments procure as part of broader industrial pipe, water main, and sewer infrastructure supply contracts. Recent solicitations show this code tagged to procurement of HDPE and PVC piping systems, fittings, couplings, and related appurtenances for water distribution, stormwater management, and sanitary sewer maintenance on as-needed inventory bases. The City of Phoenix Public Works Department and water and sewer authorities are the primary issuing bodies, soliciting three-year supply contracts with firm pricing and 24- to 48-hour delivery requirements from local inventory. Tube unions appear in these contracts as component parts within larger fittings and coupling assemblies rather than as standalone line items; the code designation itself does not isolate this product as a discrete procurement focus.

Recent activity clusters in Arizona and Georgia. The City of Phoenix issued two nearly identical IFBs (IFB 26-SW-0379 in August 2026 and IFB 27-SW-0447 in September 2026) for industrial pipe, fittings, and equipment supply to Phoenix Aviation Department airports, both with three-year terms commencing December 2026 and two optional one-year extensions. The City of Augusta, Georgia issued ITB 27-116 (due September 29, 2026) for HDPE pipe and coupling materials for down-drain installation, and the Douglasville-Douglas County Water and Sewer Authority issued IFB 327 (due October 7, 2026) for annual water and sewer pipe fittings and related inventory. The County of DeKalb, Georgia solicited quick insertion valves, tapping sleeves, and gate valves under ITB 2026-034-ITB (due August 27, 2026) on a three-year multiyear contract. All awards require DBE participation documentation where federal funds or transit authority grants apply; local-bidder preferences and MWBE utilization plans are common state-level requirements in Georgia jurisdictions.
