UNSPSC 40175300: Specialized pipe fittings and flanges

UNSPSC 40175300 Specialized pipe fittings and flanges is a Class code under which state and local governments procure custom and pressure-rated junction and transition fittings for water, wastewater, and stormwater infrastructure—particularly wyes, tees, reducers, and flanged assemblies in materials including PVC, HDPE, cast iron, and brass. Recent solicitations show demand concentrated in sanitary sewer rehabilitation and water-distribution upgrades, where fittings anchor point repairs, mainline replacements, and service-lateral connections. The code sees activity from county sanitation districts, municipal departments of public works, and county transportation and public works departments. Santa Clara County has posted multiple opportunities under related codes in 2026, suggesting sustained infrastructure renewal activity in that jurisdiction.

Recent representative opportunities include County Sanitation District No. 2-3's Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026), which called for removal and replacement of twenty-seven 4"×6" wyes, two 4"×8" wyes, and two 4"×10" wyes as part of sewer mainline point repairs and extensions in Santa Clara County's unincorporated eastern foothills, and the City of Brockton, Massachusetts Department of Public Works bid for lead-free brass fittings (BD261143PRO15PRO15129470, due June 4, 2026), which required material-composition certifications and lead-free compliance documentation for water-system components. Geographic activity in 2026 centers on California (Santa Clara County) and Massachusetts (Brockton), with procurement activity spanning spring through late summer. Issuing bodies range from special districts and municipal departments to county public-works offices, reflecting the distributed nature of water and wastewater infrastructure ownership across state and local jurisdictions.
