NIGP 65906: Adapters

NIGP 65906 Adapters is an Item code under which state and local governments procure specialized pipe fittings and connection components for water and sewer infrastructure projects. The scope of work focuses on manufactured adapters—particularly MJS (bell and spigot) adapters, wyes, and similar fittings—that join sections of PVC, HDPE, and other piping materials in gravity-fed utility systems. Recent solicitations show adapters being purchased as discrete line items within larger infrastructure rehabilitation and replacement projects rather than as standalone commodity buys. Issuing bodies include county utilities departments, sanitation districts, state environmental agencies, and county purchasing divisions acting on behalf of water resources and public works divisions. Gwinnett County Department of Financial Services, Santa Clara County Sanitation District No. 2-3, Pinellas County in Florida, and the Maryland Environmental Service have each posted opportunities under or aligned with this code in the past four months.

The most recent activity appears concentrated in California and Georgia, with secondary activity in Florida and Maryland.
