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 (Commodity) addresses sealing and closure products for infrastructure and equipment maintenance, though recent state and local opportunities show minimal direct procurement activity under this code. The one substantive match in the recent-opportunities block is the Maine Department of Transportation's RFQ 17A 260427-275 for bridge joint seals and related materials, which encompasses compression seals in multiple sizes (1/2" to 6" widths), silicone coated pre-compressed foam seals, non-brand-specific gland seals, and supporting materials such as lubricant adhesive, sealant, primer, backer rod, splice adhesive, and transition or corner materials. Delivery is required to nine MaineDOT locations across five regions throughout Maine, with pricing due June 1, 2026, at 4:00 p.m. EST via the State of Maine's Advantage Vendor Self Service system on a FOB Destination basis. The initial contract period runs from June 15, 2026, through June 30, 2027, with four optional one-year extension periods through June 30, 2031, and the State anticipates making one award to the lowest qualified bidder. Bidders must provide manufacturer literature, equivalency documentation for alternative products, and warranty information, with quoted prices remaining firm for a minimum of one year. Municipal subdivisions and school districts in Maine may be permitted to access the resulting contract at the State's negotiated pricing if the bidder consents.

The remaining recent opportunities in the block—a Williamson County relocation notice, a Sourcewell law enforcement equipment RFP, Brevard County fleet parts inventory management, Atlanta heavy-duty trailer repair services, and Sarasota County automotive parts—are unrelated to lip seal procurement and reflect misclassification or posting error. The code shows limited recent relevant activity in state and local procurement. Geographic concentration cannot be determined from the single qualified opportunity, though Maine's MDOT is the identifiable buyer. Firms tracking this code should monitor for bridge maintenance and expansion projects at state DOT offices and municipal public works departments, where joint seal procurement typically clusters with broader construction or repair RFPs.
