UNSPSC 31410000: Seals

Devices used to eliminate or control the leakage of liquids and or gases while preventing the entrance of external contaminants

UNSPSC 31410000 Seals is a Family code covering bridge expansion joint seals, automotive gaskets, and related sealing materials that state and local governments procure for infrastructure maintenance, fleet operations, and facility repairs. The code encompasses compression seals, silicone-coated foam seals, gland seals, and supporting materials such as sealants, primers, backer rod, and adhesives used in bridge construction and heavy equipment repair. State and local issuing bodies soliciting under this code include state departments of transportation, county purchasing departments, city fleet and public works offices, and school districts managing automotive and facility maintenance inventories. The scope ranges from single-purpose bridge joint seal contracts to multi-category facility and fleet repair agreements where seals are one line item among many.

Recent activity in this code centers on Maine and Georgia. The Maine Department of Transportation, through the State of Maine Department of Administrative and Financial Services, issued RFQ 17A 260427-275 in May 2026 to establish a Master Agreement for bridge joint seals and related materials, with 76 line items across compression seals (23 sizes from 1/2" to 6"), silicone-coated foam seals (23 sizes), gland seals (23 sizes), and supporting materials, delivery required to nine MaineDOT locations across five Maine regions, quotations due June 1, 2026, with a contract period through June 30, 2027 and four optional one-year extensions. The City of Atlanta Department of Public Works issued an Invitation for Bid (IFB) in March 2026 (due May 1, 2026) for heavy-duty trailers, repair services, and parts that includes seals and gaskets as component materials. The Sarasota County School Board's Bid #26-0124, posted January 2026 with response due February 12, 2026, established a one-year automotive and light truck repair parts agreement covering 19 OEM manufacturers where seals, gaskets, and related components represent a subset of covered commodities. No recent opportunities under the code have been posted in Texas, Florida (outside the school district context), or the upper Midwest in the source material.
