NIGP 65933: Couplings

NIGP 65933 Couplings is an Item code covering pipe couplings and related fittings that state and local governments procure for water distribution and sanitary sewer infrastructure projects. Recent solicitations show state and local buyers purchasing compression couplings, service saddles, wyes, and valve insertion components as part of mainline replacement, rehabilitation, and extension work on pressurized and gravity sewer systems. Issuing bodies soliciting under this code include county utilities and sanitation districts, municipal water departments, and county public works agencies across multiple states. Work ranges from individual component procurement on annual supply contracts to large-scale infrastructure rehabilitation projects where couplings and fittings are specified as discrete line items within broader pipe replacement and system improvement scopes.
