UNSPSC 31163022: Clamp coupling

A type of coupling sometimes called a compression coupling or a ribbed coupling. It is a modification and an improvement on the sleeve coupling.

UNSPSC 31163022 Clamp coupling is a Commodity code that covers mechanical fastening and connection components used in industrial and infrastructure assembly work. State and local governments procure clamp couplings primarily as materials within larger construction, facility maintenance, and infrastructure projects rather than as standalone supply orders. Issuing bodies include county departments, city public works divisions, and special-purpose facility authorities that source these components as part of capital projects, equipment installations, and system upgrades. The work solicited under this code is embedded in broader construction, HVAC, plumbing, electrical, and low-voltage infrastructure scopes where clamp couplings serve as connecting hardware for conduit, piping, raceways, and similar systems.

DeKalb County's 2026-076-ITB for reconstruction of the DeKalb Tennis Center (due July 13, 2026) represents recent activity in this space, though the opportunity's primary focus is IT and low-voltage infrastructure installation rather than clamp coupling procurement as a line item. The ITB scope includes furnishing and installing conduit, pathways, raceways, and related infrastructure where clamp couplings would be specified components. Geographic activity is concentrated in the Southeast, with the DeKalb County opportunity indicating Georgia procurement. Recent solicitation volume under this Commodity code appears limited, reflecting that clamp couplings are typically sourced as subordinate materials within larger construction or infrastructure RFPs and ITBs rather than as direct procurements.
