NIGP 81558: Pressure Gauges (Not Hospital, Laboratory, and Refrigeration)

NIGP 81558 Pressure Gauges (Not Hospital, Laboratory, and Refrigeration), an Item code, encompasses pressure measurement instruments and associated mounting, transmission, and control equipment that state and local governments procure for municipal water and wastewater treatment, industrial process monitoring, and infrastructure management. Recent solicitations show purchasing extends beyond simple dial gauges to pressure transmitters, pressure switches, diaphragm seals, remote indicators, mounting hardware, junction boxes, and cable assemblies from manufacturers including Ashcroft, Dwyer, Honeywell, Emerson, and Siemens. Issuing bodies include city water and utilities departments and county procurement offices; these agencies typically require vendors to function as local stocking distributors capable of same-day or next-business-day replacement-parts fulfillment and to carry minimum three-year history supplying similar instrumentation to water and wastewater utilities. Contracts are often framed as multi-year fixed-price agreements with annual price-increase review windows and DBE participation tracking, and awards typically go to the lowest responsive and responsible offeror, with the issuing body reserving the right to award by line item, in groups, or to multiple vendors.
