NIGP 81545: O-Rings

NIGP 81545 O-Rings, an Item code, covers elastomer sealing rings that state and local governments procure as component parts for machinery, equipment, and fluid-system maintenance across facilities and vehicle fleets. O-rings are standard inventory items bought as replacements during preventive maintenance and repair of pumps, compressors, hydraulic systems, and rotating equipment in water systems, wastewater treatment plants, public works departments, transit authorities, and facilities management operations. The code captures both bulk procurement of assorted o-ring kits and specific-size orders placed through maintenance supply vendors or direct purchase from manufacturers. Issuing bodies are predominantly municipal public works departments, county facilities and fleet maintenance operations, and special-purpose water and wastewater authorities that stock o-rings in standardized sizes and material compositions (typically nitrile rubber, EPDM, or silicone) for routine wear-and-tear replacement.
