UNSPSC 31411700: Mechanical seals

Seals designed to prevent leakage between a rotating shaft and its housing.

UNSPSC 31411700 Mechanical seals is a Class code covering pump seals, compression seals, and related hydraulic or fluid-containment seal products that state and local governments procure for infrastructure maintenance, equipment repair, and fleet operations. Recent state and local solicitations show demand for bridge joint seals, pump repair components, and seal materials used in water, transportation, and utility systems. Issuing bodies include state departments of transportation, municipal utilities, and county administrative departments. The procurement mix spans single-source awards for specialized pump products, competitive RFQs for bulk seal supplies, and cooperative purchasing frameworks that aggregate demand across multiple jurisdictions.

Geographic activity centers on Maine, Florida, and the Pacific Northwest, with evidence of multi-state sourcing requirements. The Maine Department of Transportation issued RFQ 17A 260427-275 in May 2026 (due June 1, 2026) to establish a Master Agreement for bridge joint seals and related materials—76 line items including compression seals in 23 sizes, silicone coated foams, gland seals, lubricants, adhesives, and backer rod, with delivery to nine MaineDOT locations across five regions and an initial contract term through June 30, 2027 with four optional one-year extensions. The City of Port Orange, Florida published a Notice of Intent to Award sole-source procurement SS2620CW in September 2026 for NOV Chemineer Moyno pump repair products and parts through an authorized dealer, with an estimated annual contract value of $500,000 and a response deadline of September 16, 2026. Sourcewell, a Minnesota cooperative purchasing vehicle, issued RFP 061626 in May 2026 (due June 16, 2026) for law enforcement equipment available to participating entities across multiple states, though the sealed-products applicability to that opportunity is unclear from available documentation.
