UNSPSC 31411803: Capsule diaphragm seal

A type seal that is internally sealed, with the fill fluid within the capsule in the upper housing

UNSPSC 31411803 Capsule diaphragm seal is a Commodity code that shows minimal recent activity directly aligned with its stated scope; most recent state and local opportunities tagged to this code involve unrelated procurement categories. The one relevant exception is the Maine Department of Transportation's RFQ for bridge joint seals and related materials (RFQ 17A26042700000000000275, due June 1, 2026), which solicits compression seals, silicone coated foam seals, gland seals, and supporting materials such as lubricant adhesive, sealant, primer, and backer rod across 76 line items measured in linear feet and delivered to nine MaineDOT locations statewide. The remaining opportunities in the recent block—a Williamson County administrative relocation notice, a Sourcewell cooperative law enforcement equipment RFP, a Brevard County fleet inventory management services IFB, an Atlanta heavy-duty trailers repair and parts IFB, and a Sarasota County schools automotive parts supply bid—fall outside capsule diaphragm seal scope and do not represent typical purchasing activity under this code.

The code's recent activity is concentrated in Maine, with the MaineDOT procurement representing the principal documented state and local opportunity. That RFQ establishes a Master Agreement running from June 15, 2026 through June 30, 2027 with four optional one-year extensions available, requires FOB Destination pricing including freight and delivery to multiple locations, and anticipates a single award to the lowest qualified bidder. Quotations must be submitted via the State of Maine's Advantage Vendor Self Service system by June 1, 2026 at 4:00 p.m. EST, with bidders required to provide manufacturer literature, equivalency documentation, warranty information, and a Responsible Bidder Form. The solicitation permits municipal, political subdivisions, and school districts in Maine to access the resulting contract at state-negotiated pricing. The code otherwise shows no current activity from school districts, counties, cities, or transit authorities that would support a broader characterization of issuing-body concentration or geographic spread beyond the Maine example.
