UNSPSC 31411806: O-ring seal

O-rings seals are very commonly found in pumps, cylinders, connectors and valves, helping to seal joins between separate parts and prevent leaking of fluids and gases. They're used with static, dynamic, hydraulic and pneumatic components, making them an especially versatile solution to a very widespread engineering issue.

UNSPSC 31411806 O-ring seal, a Commodity code, encompasses elastomeric sealing components that state and local governments procure for infrastructure maintenance, fleet asset management, and equipment repair operations. State and local buyers under this code include departments of transportation, county and city fleet services, school districts, and public works agencies. The scope of work spans compression seals, silicone-coated foam seals, gland seals, and supporting sealant materials used in bridge joint systems, automotive repairs, and heavy-equipment maintenance. Issuing bodies range from state transportation departments managing statewide infrastructure networks to county fleet services managing vehicle and equipment inventories, and school districts maintaining automotive repair supply agreements.

Recent state and local activity under this code centers on infrastructure and fleet maintenance. The Maine Department of Transportation, through the State of Maine Department of Administrative and Financial Services, issued RFQ 17A260427-275 on May 18, 2026 (due June 1, 2026) to establish a master agreement for bridge joint seals and related materials across 76 line items, including compression seals in 23 sizes, silicone-coated foam seals, and gland seals, with delivery to nine MaineDOT locations across five regions and an initial contract term running June 15, 2026 through June 30, 2027 with four optional one-year extensions. The School Board of Sarasota County, Florida issued Bid #26-0124 on January 23, 2026 (due February 12, 2026) for automotive and light truck repair parts with manufacturer discounts across 19 OEM product lines. Geographic activity appears concentrated in Maine and Florida based on recent postings, though the code likely sees broader application across state DOT networks and municipal fleet operations nationwide. One posting identified as related to this code (Williamson County Purchasing Department relocation notice of July 14, 2026) contains no procurement scope and is not actionable.
