UNSPSC 23153703: Hydraulic tensioning system tools

Hydraulic tensioning systems are hydraulic tools that use stretching to tighten studs. Once a stud is stretched, a nut is then put on the joint. Then the load on the stud is removed resulting in a clamping force on the now bolted joint.

UNSPSC 23153703 Hydraulic tensioning system tools (Commodity) encompasses the supply and service of hydraulic system components—cylinders, pumps, hoses, valves, and associated fittings—along with on-site and mobile repair and fabrication services that state and local governments procure to maintain heavy equipment fleets. Recent solicitations show that this code covers both replacement parts inventory and responsive repair services; state and local buyers frame these needs as managing hydraulic systems across refuse collection vehicles, medium and heavy-duty trucks, construction equipment, and specialized municipal machinery such as valve exercisers. Cities and counties are the primary issuing bodies, supplemented by transit authorities and special-purpose districts; repeat buyers include the City of Phoenix, Orange County Florida, and Sacramento County. The City of Atlanta issued IFB MS-IFB/DPW/2609-1270096 on October 8, 2026 with a response deadline of October 21, 2026, soliciting hydraulic cylinders, pumps, hoses, fittings, components, and on-site and mobile repair services. Sacramento County posted RFB 2026-RFB-0104 on October 2, 2026, requesting a single new skid-mounted valve exerciser equipped with hydro-excavation and vacuum systems for its Water Agency, with bids due October 30, 2026 and local business and micro-business preferences in effect.

Geographic activity concentrates in California, Florida, and Arizona, with recent opportunities from Phoenix, Orange County, Sacramento County, Tucson, and the City of Atlanta. The City of Phoenix Public Works Department issued IFB 27-FSD-0353 on August 14, 2026 for hydraulic hose repair and replacement services on an as-needed basis across multiple service centers, with a three-year initial term commencing in November 2026 and a Small Business Participation Plan in effect. Orange County, Florida posted IFB Y26-195 on August 5, 2026 for on-site and off-site hydraulic and pneumatic hose repair with a response deadline of September 8, 2026 and Service Disabled Veteran Business Ordinance preference available; the five-year contract requires twenty-four-hour mobile coverage and two-hour emergency response. Sacramento County issued RFP 2026-RFP-0032 in May 2026 with an estimated annual value of $1,200,000 for hydraulic system parts repair, replacement, and fabrication services across county fleet operations, requiring an authorized Hypro parts dealer with same-day availability within 40 miles. The City of Tucson solicited proposals under RFP 250013 for repair and rebuild of Parker V20 and V35 valves and hydraulic cylinders with an estimated annual spend of $125,000 and potential for four one-year extensions.
