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

NIGP 65997 Pipe Fittings, Misc. (Not Otherwise Classified) is an Item code capturing specialized fitting products state and local governments procure for water infrastructure, stormwater systems, and municipal maintenance applications. Recent solicitations reveal that jurisdictions buy ductile iron pipe nipples with polyethylene coating, PVC and ductile iron fittings with flanged connections, mechanical joint fittings for water mains, fire hydrant components, backflow preventers, and miscellaneous appurtenances specified to approved manufacturer standards—typically ANSI, AWWA, or construction specification manual requirements. The issuing bodies include water districts (North Texas Municipal Water District), county water resources departments (Gwinnett County), municipal public works and utilities divisions (City of Phoenix, City of Palm Bay, City of Sarasota), county infrastructure agencies (Orange County Florida), and housing authorities (Housing Authority of the City of Alameda). Water systems and stormwater rehabilitation projects dominate the recent activity, with periodic procurement of replacement and upgrade components for aging infrastructure.

Geographic concentration is heaviest in Florida (Orange County, Palm Bay, and Sarasota) and Georgia (Gwinnett County, Lavonia, Calhoun), with additional activity in California (Phoenix, Alameda) and Texas (North Texas Municipal Water District, Dallas). Representative recent opportunities include the City of Phoenix Public Works' three-year as-needed supply contract for HDPE and PVC pipe with miscellaneous fittings under IFB 26-SW-0379, due August 12, 2026, requiring 24- to 48-hour delivery and local inventory maintenance; the City of Sarasota materials-only bid for pipe and fittings conforming to its Potable Water Approved Material List under ITB 26-31JS (deadline passed June 16, 2026); and Gwinnett County's informal written quotation for ductile iron pipe nipples with PE coating in four size configurations, due April 23, 2026. Larger infrastructure projects such as water main relocation (City of Calhoun, Georgia) and water treatment plant upgrades (City of Lavonia, Georgia) bundle fittings procurement with construction contracts. Most solicitations specify firm pricing for multi-year terms, require delivery within 24 to 90 business days depending on order size and urgency, and mandate compliance with American standards and local approved materials lists.
