UNSPSC 40175300: Specialized pipe fittings and flanges

UNSPSC 40175300 Specialized pipe fittings and flanges, a Class code, encompasses lead-free brass fittings, mechanical joint restraining devices for ductile iron and PVC pipe, flanged cast iron fittings, and water system components that state and local governments procure for municipal water infrastructure, distribution networks, and facility maintenance. Recent solicitations show municipalities buying these items through competitive bid and RFQ processes to stock inventory for ongoing water operations and capital projects. Issuing bodies include city water departments, county public works and procurement offices, and municipal purchasing departments. The work spans both routine supply contracts with multi-year terms and support for larger pavement and infrastructure rehabilitation projects where these fittings serve as components in construction specifications.

Recent activity concentrates in California, Florida, Massachusetts, and Arizona. The City of Brockton, Massachusetts Department of Public Works posted an IFB on May 18, 2026 (due June 4, 2026) for lead-free brass fittings meeting detailed water system technical and lead-free compliance standards; the same city posted a concurrent bid for copper tubing on the same timeline. Palm Beach County Board of County Commissioners issued IFB 26-038/RR on April 22, 2026 (due June 4, 2026) for mechanical joint restraining devices across two lots—solid design restraining devices for 3-inch to 54-inch ductile iron pipe (918 units estimated) and solid ring design devices for 3-inch to 24-inch PVC pipe (912 units estimated)—with an anticipated contract value of $200,000 over the initial twelve-month term and SBE ten-percent price preference eligibility. The City of Tampa Purchasing Department issued RFQ 26-P-00152 in early March 2026 for Standard Class 125 flanged cast iron fittings (five line items across specific sizes and configurations) with FOB Destination delivery within ten days. The City of Phoenix Water Services Department solicited water pipe and miscellaneous fittings (15 product groups including flanges, couplings, clamps, and gate valves totaling over 21,000 units across a five-year term) under IFB 260217, with a non-mandatory pre-offer conference held February 4, 2026 and sealed offers due February 19, 2026; the contract requires bidders to have five years of operational history, maintain local inventory, and comply with DBE and E-Verify requirements.
