NIGP 65933: Couplings

NIGP 65933 Couplings, an Item code, covers stainless steel and ductile iron couplings and related bypass components supplied to state and local water utilities, municipalities, and county water authorities for meter assemblies, water distribution systems, and septic abatement projects. State and local governments buy couplings as part of larger water infrastructure procurements—replacement of meter bypass systems, pavement rehabilitation projects that include utility coordination, and materials packages for water and sewer operations. Recent solicitations show couplings embedded in comprehensive water system contracts rather than standalone coupling purchases; the City of Phoenix Water Services Department solicited straight water meter couplings as one line item (over 21,000 units) within a broader five-year IFB for water pipe and miscellaneous fittings posted February 23, 2026, and Volusia County included brass fittings and related components in its Materials for Water and Sewer Operations bid (ITB 26-B-42LS) posted March 9, 2026. Issuing bodies include municipal water departments (Phoenix Water Services), county utilities (Jackson County Utility Authority, Volusia County, Gwinnett County in Georgia), and regional group purchasing cooperatives (Berkshire Regional Group Purchasing Program in Massachusetts representing 32 Berkshire County municipalities). All metal components are generally required to meet ANSI/AWWA standards, be American-made where specified, and conform to potable water certifications (NSF 60 and 61).

Geographic activity centers on Arizona, California, Florida, Georgia, and Massachusetts, with Phoenix and Volusia County as active repeat procurers in the water operations space. The Berkshire Regional Group Purchasing Program's FY27-04 Culvert Products category (ITB posted April 19, 2026, due April 2, 2026) grouped culvert products alongside 19 other highway materials for 32 municipalities across Northern, Central, and Southern Berkshire County subsections, indicating cooperative purchasing models where couplings and related fittings may appear within multi-category awards. Franklin County, Georgia's water system booster pump station renovation (ITB PE77589NONST2026000000005, due March 24, 2026) required pumps, piping, and instrumentation but illustrates the range of water infrastructure projects where couplings are supporting components. The City of Phoenix's five-year water pipe and miscellaneous fittings contract (IFB 260217, due February 19, 2026) is the most recent direct sourcing activity; bidders must have five years' operational history, local inventory, next-day delivery capability on captive parts, and NSF certifications, with awards made to lowest responsive and responsible bidder across 15 product groups.
