UNSPSC 31411802: Clamped diaphragm seal

A type seal clamped between the upper and lower housing allowing it to be removed and replaced easily

UNSPSC 31411802 Clamped diaphragm seal is a Commodity code, but the recent state and local solicitations tagged under it show limited activity directly aligned with the nominal scope. The one concrete opportunity relevant to seals is the Maine Department of Transportation's RFQ 17A 260427-275 (posted May 18, 2026, due June 1, 2026) for bridge joint seals and related materials — a Master Agreement covering 76 line items including compression seals (23 sizes, 1/2" to 6" width), silicone coated pre-compressed foam seals (23 sizes), non-brand-specific gland seals (23 sizes), and supporting materials such as lubricant adhesive, sealant, primer, backer rod, splice adhesive, and transition/corner materials. The remaining opportunities in the dataset — a Brevard County fleet inventory management RFQ, an Atlanta Department of Public Works trailers and repair services IFB, a Sarasota County Schools automotive parts bid, and a Sourcewell law enforcement equipment RFP — are misaligned with clamped diaphragm seals and reflect tagging errors rather than genuine procurement demand under this code.

The Maine solicitation, issued by the State of Maine Department of Administrative and Financial Services on behalf of the Maine Department of Transportation, anticipates delivery to nine MaineDOT locations across five regions, with an initial contract period from June 15, 2026, through June 30, 2027, and four optional one-year extensions available through June 30, 2031. All seal products are measured in linear feet with estimated evaluation quantities of 100 linear feet per line item; supporting materials are evaluated at 1 unit each. Quotations were due June 1, 2026, at 4:00 p.m. EST via the State of Maine's electronic procurement system on an FOB Destination basis. The RFQ does not identify set-aside designations, and pricing must remain firm for a minimum of one year. Beyond the Maine opportunity, this code shows no other recent state and local solicitations with genuine demand for clamped diaphragm seals or closely related products.
