UNSPSC 31163004: Miniature couplings

UNSPSC 31163004 Miniature couplings is a Commodity code that represents small-diameter hydraulic, pneumatic, or fluid-transfer coupling products used in water infrastructure, HVAC systems, and industrial equipment. Recent state and local solicitations under this code show minimal direct activity; of the nine opportunities tagged with or relevant to this code, only one—the City of Phoenix Water Services procurement (IFB260217)—explicitly names couplings as a line item, requesting over 21,000 units of straight water meter couplings among 15 product groups for water distribution systems. The remaining opportunities tag broader categories such as water and sewer materials, culvert products, or HVAC equipment where couplings may be incidental components rather than primary deliverables. Issuing bodies include municipal water utilities (City of Phoenix, City of Phoenix Water Services), county water authorities (Jackson County Utility Authority, Volusia County, Gwinnett County), and cooperative purchasing consortiums (Berkshire Regional Group Purchasing Program in Massachusetts). The code shows no concentration among repeat buyers; each jurisdiction appears once or twice in the recent block.

Activity is geographically dispersed across California, Massachusetts, Georgia, Florida, and Arizona, with no dominant region. The most substantive recent opportunity is the City of Phoenix Water Services IFB260217 for water pipe and miscellaneous fittings, posted February 23, 2026, due February 19, 2026, a five-year contract commencing May 1, 2026, which includes couplings as one of 15 product groups and requires bidders to maintain local inventory with next-day delivery capability and one-year warranties. The Jackson County Utility Authority request for written quotes (solicitation 3170036136) posted June 30, 2026, due July 8, 2026, for materials for the South Central Septic Abatement Project with BABA certification required, suggests potential coupling applications in wastewater infrastructure but provides minimal scope detail. The code's low visibility in recent solicitations and the tendency of jurisdictions to bundle couplings with broader water, sewer, or HVAC procurements rather than solicit them as standalone line items indicates limited direct procurement momentum under this specific commodity classification.
