UNSPSC 31181704: Stuffing box

A type of gland seal used to prevent leakage of fluid, such as water or steam, between sliding or turning parts of machine elements.

UNSPSC 31181704 Stuffing box is a Commodity code, but the recent state and local opportunities posted under this tag show little alignment with the nominal scope. The solicitations span vehicle diagnostic services, transit spare parts, school bus air-conditioning maintenance, inventory management systems, mechanical services, wastewater equipment parts, and OEM parts across multiple equipment families — none of which correspond to stuffing box components or mechanical sealing assemblies. The code appears to be a catch-all or mislabeling artifact in state and local procurement systems, with no discernible pattern of genuine stuffing-box procurement activity.

Issuing bodies include school districts (Hillsborough County Public Schools, Pinellas County School District, Parkway School District), transit authorities (Charlotte Area Transit System), state departments (Illinois Department of Transportation, Texas Department of Transportation, Texas Health and Human Services Commission), counties (Jackson County Missouri, Lee County Florida), cities (Eugene Oregon, Fort Myers Florida), and the Commonwealth of Kentucky. Geographic spread spans Florida (Hillsborough, Lee, Pinellas counties; Fort Myers, Fruitville), North Carolina (Charlotte), Texas (Houston, Austin), Illinois, Kentucky, Oregon, and Missouri. Representative recent opportunities include Hillsborough County Public Schools ITQ 26252-ITQ-DST for Chevrolet diagnostic and repair services (response date July 10, 2026, extended by Addendum 1 issued July 1, 2026); Charlotte Area Transit System RFP seeking S70 LRV conical spring spare parts (due November 2, 2026); City of Eugene RFP 20272006 for a Fleet Vehicle and Equipment Parts Price Agreement covering six vehicle and equipment parts categories (due August 6, 2026); and Pinellas County School District ITB 26-AM-016 for motor vehicle brake parts with an estimated contract value of approximately $190,000 annually (due August 24, 2026). The code shows recent activity but does not reflect the nominal commodity scope—pursue only if your firm supplies vehicle diagnostics, fleet maintenance, transit components, or allied automotive and equipment parts under broader procurement frameworks that may misclassify line items at the commodity tier.
