UNSPSC 40183102: Tube tee

UNSPSC 40183102 Tube tee is a Commodity code naming a single fitting product used in water, sewer, stormwater, and industrial piping systems. State and local governments procure tube tees as part of broader supply contracts for pipe, fittings, and appurtenances used in infrastructure maintenance, replacement, and new construction. The issuing bodies are primarily municipal water and sewer utilities, county sanitation districts, and city public works departments. Recent solicitations show tube tees embedded within larger material-supply agreements rather than purchased as a line item standing alone; for example, the City of Phoenix Public Works Department solicits HDPE and PVC pipe along with fittings (elbows, couplings) for three-year supply contracts, and the Douglasville-Douglas County Water and Sewer Authority bundles sewer couplings and fittings into annual inventory-material requests covering multiple pipe sizes and component types. The Commodity code itself does not distinguish individual fitting types—tees, wyes, elbows, couplings—so procurement under 40183102 overlaps with adjacent codes covering other fittings, and tube tees appear as one specification among many within larger supply-chain and infrastructure-repair solicitations.

Geographic activity concentrates in the Southeast and Southwest, with recent solicitations from Georgia (DeKalb County quick-insertion valves and fixtures; Augusta stormwater couplings and end sections; Calhoun water-main materials including mechanical fittings), California (Santa Clara County sewer-mainline replacements with PVC wyes and tees; Sanitation District No. 2-3 sewer repairs using 4"×6", 4"×8", and 4"×10" wyes), and Florida (Palm Bay stormwater outfall replacement; Sarasota potable-water main materials). The City of Phoenix appears twice in the opportunity set (IFB 27-SW-0447 and IFB 26-SW-0379, both posted in 2026 for three-year industrial-pipe supply covering airport operations), indicating repeat procurement of fittings on established schedules. Tube tees are typically purchased as components within multiyear supply or construction-materials contracts with firm fixed pricing, 24- to 60-day delivery windows, local-inventory requirements, and as-needed ordering. Issuing bodies enforce compliance with local DBE programs, FAA Grant Assurances where airports are involved, and materials-approval checklists specifying approved manufacturers and alternate-submission protocols.
