UNSPSC 31411705: Lip seal

An annular shaft seal for sealing against oil which is flexible and uses an interference fit on the shaft and deformation stress to maintain the seal.

UNSPSC 31411705 Lip seal is a Commodity code that encompasses sealing components used in pump systems, mechanical equipment, and infrastructure applications. State and local governments buy lip seals primarily for maintenance and repair of water infrastructure, industrial equipment, and transportation systems. Recent solicitations show purchasing for original equipment manufacturer (OEM) pump repair parts, bridge joint seals (compression and silicone-coated foam variants), and associated sealing materials such as adhesives, primers, and backer rods. Issuing bodies include state transportation departments, municipal utilities, and county water authorities. The procurement activity reflects both routine maintenance purchasing and larger infrastructure asset management initiatives requiring standardized seal products across multiple locations and equipment types.

Recent activity centers in Maine and Florida. The State of Maine Department of Transportation issued a Request for Quotation (RFQ 17A26042700000000275) due June 1, 2026, for bridge joint seals and related materials — 76 line items spanning compression seals, silicone-coated foam seals, and supporting products such as lubricant, adhesive, sealant, and backer rod, with delivery to nine MaineDOT locations across five regions and a Master Agreement term running through June 2027 with optional extensions to 2031. The City of Port Orange, Florida published a Notice of Intent to Award on September 16, 2026, for NOV Chemineer Moyno pump products and repair services under a sole-source procurement framework with an estimated annual contract value of $500,000, seeking to confirm whether authorized alternative dealers exist in Florida, Alabama, Georgia, and Tennessee. These opportunities indicate sustained demand for both specialized OEM replacement seals and commodity-grade sealing materials in state transportation and municipal utility applications.
