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 (Family) encompasses bridge joint seals, compression seals, foam seals, gland seals, and related sealant materials and accessories that state and local transportation departments and municipalities procure for infrastructure maintenance and repair. The code sees activity across state departments of transportation and municipal public works operations, with recent solicitations spanning multi-year Master Agreements and sole-source renewals for ongoing maintenance.

The Maine Department of Transportation, operating through the State of Maine's Office of State Procurement Services, issued an RFQ (RFQ 17A 260427-275) in May 2026 for a Master Agreement covering 76 line items of bridge joint seals and supporting materials—compression seals in 23 sizes, silicone coated pre-compressed foam seals in 23 sizes, non-brand-specific gland seals in 23 sizes, and ancillary items such as lubricant adhesive, sealant, primer, backer rod, and splice adhesive—with delivery required to nine MaineDOT locations across five regions and a contract period running from June 15, 2026, through June 30, 2031, with four optional one-year extensions. The City of Port Orange, Florida posted a Notice of Intent to Award for sole-source renewal of NOV Chemineer Moyno pump repair products and parts in September 2026, with an estimated annual contract value of $500,000. Activity is concentrated in Maine and Florida, with the Maine procurement as the most recent competitive effort and the Florida notice reflecting the maintenance renewal cycle for specialized equipment repair.
