UNSPSC 40183105: Tube nipple

UNSPSC 40183105 Tube nipple is a Commodity code under which state and local governments procure industrial and municipal piping fittings, couplings, and related assembly components for water, sewer, and stormwater infrastructure maintenance and construction. Recent solicitations show the code captures supply contracts for HDPE and PVC pipe fittings, quick-insertion valves, resilient wedge gate valves, tapping sleeves, wyes, elbows, couplings, and ancillary materials ordered on an as-needed basis for utility system repairs and mainline replacements. City water and sewer authorities, county utilities departments, and municipal public works offices are the dominant issuing bodies, often establishing multi-year blanket supply agreements with firm pricing and rapid-delivery requirements to support emergency repairs and routine maintenance. The City of Phoenix Public Works Department has solicited twice under closely related scope (IFB 26-SW-0379 in August 2026 and the follow-on IFB 27-SW-0447 in September 2026), signaling repeat demand from a single large metropolitan utility.

Georgia and Florida dominate recent activity. The City of Augusta issued ITB 27-116 (bids due September 29, 2026) for HDPE pipe, couplings, and end sections with mandatory minority and women-owned business enterprise utilization plans and a local-bidder preference for awards under $100,000. The Douglasville-Douglas County Water and Sewer Authority in Georgia solicited IFB 327 (bids due October 7, 2026) for annual water and sewer pipe fittings and related inventory materials on a one-year contract with four optional renewal periods. DeKalb County, Georgia issued ITB 2026-034-ITB (bids due August 27, 2026) for quick insertion valves and tapping sleeves under a three-year multiyear contract. The City of Calhoun, Georgia procured materials for water main relocation (bids due June 18, 2026) including ductile iron and PVC piping with mechanical joint fittings. In California, Santa Clara County's Sanitation District No. 2-3 issued bids (due September 17, 2026) for sewer infrastructure rehabilitation including removal and replacement of service connection wyes in multiple diameters and mainline extensions using PVC and HDPE pipe. Contracts typically run one to three years with as-needed purchasing, firm fixed pricing for the term, delivery within 24–96 hours, local inventory requirements, and compliance with federal nondiscrimination and E-Verify provisions where projects receive federal assistance.
