NIGP 65997: Pipe Fittings, Misc. (Not Otherwise Classified)

NIGP 65997 Pipe Fittings, Misc. (Not Otherwise Classified), Item tier, covers the supply of miscellaneous pipe fittings and related materials used in water, sewer, stormwater, and industrial applications. State and local governments procure under this code primarily HDPE and PVC pipe in various diameters, couplings, elbows, wyes, tees, bends, gate valves, quick insertion valves, and accessory kits on an as-needed basis for infrastructure maintenance and capital projects. Recent solicitations show activity from municipal utilities, county water and sewer authorities, public works departments, and special-purpose water and sanitation districts. The City of Phoenix Public Works Department appears as a repeat buyer, with two separate IFBs for industrial pipe and fittings issued within two months (August 2026 and September 2026). Municipal water and sewer authorities dominate the issuing-body mix, reflecting the code's core use in pipeline maintenance and replacement work.

Georgia and Arizona account for the bulk of recent activity. The City of Phoenix issued back-to-back three-year supply contracts (IFB 26-SW-0379 and IFB 27-SW-0447, response dates August 12, 2026 and September 30, 2026) for HDPE pipe 1.5" to 24" diameter, PVC pipe 0.75" to 4" diameter, elbows, couplings, glue, and hand tools with 24- to 48-hour delivery requirements and local inventory maintenance mandates.
