UNSPSC 40183107: Tube coupling

UNSPSC 40183107 Tube coupling is a Commodity code covering flexible connectors and joining assemblies used in water, sewer, and stormwater infrastructure systems. State and local governments procure tube couplings primarily as components within broader materials supply contracts for water main replacement, sewer system rehabilitation, drainage infrastructure maintenance, and emergency pipe repairs. Recent solicitations show couplings being bought alongside high-density polyethylene (HDPE) pipe, polyvinyl chloride (PVC) pipe, wyes, elbows, tees, and fittings for distribution and collection systems serving municipal water, sewer, and stormwater operations.

Solicitations under this code originate from city public works departments, county water and sewer authorities, sanitation districts, and municipal utilities across the South and Southwest. The City of Phoenix Public Works Department appears as a repeat buyer, issuing two overlapping three-year industrial pipe and fittings contracts (IFB 26-SW-0379 in August 2026 and IFB 27-SW-0447 in September 2026) covering the Phoenix Aviation Department's three airport facilities. The City of Augusta, Georgia (ITB 27-116, bids due September 29, 2026) and the Douglasville-Douglas County Water and Sewer Authority in Georgia (IFB 327, bids due October 7, 2026) solicited annual materials supplies including couplings and pipe for maintenance and rehabilitation on an as-needed basis. Santa Clara County Sanitation District No. 2-3 (ITBRDAFY260694, bids due September 17, 2026) awarded work replacing sewer mainline sections using PVC and HDPE pipes with wye couplings and service connection fittings in the unincorporated eastern foothills. Recent activity concentrates in Georgia, Arizona, and California, with secondary recent solicitations in Florida. Contracts typically run one to three years with fixed pricing, local inventory requirements where applicable, and 24-to-48-hour delivery windows or sixty-day fulfillment for scheduled materials. DBE, MBE, and WBE participation goals and local-bidder preferences appear in Georgia and California procurements.
