UNSPSC 31163031: Sellers coupling

A coupling that tightens the conical shaped wedge with the slit between the two axes and uses the friction force with the shaft by the tightening of the taper the bolt.

UNSPSC 31163031 Sellers coupling is a Commodity code covering connection fittings and threaded or flanged coupling devices used in plumbing, mechanical, and utility infrastructure systems. State and local governments procure these components as part of broader construction, renovation, and infrastructure maintenance projects where they serve as critical connection points in piping, ductwork, and conduit systems. Issuing bodies span county departments, municipalities, and special-purpose districts managing facilities, utilities, and capital projects.

The most recent activity in the dataset shows limited direct procurement of sellers coupling as a discrete line item. A DeKalb County, Georgia ITB (2026-076-ITB) for reconstruction of the DeKalb Tennis Center, due July 13, 2026, includes IT and low voltage infrastructure work that would incorporate coupling components as part of broader conduit, pathway, and cabling installation, though the solicitation emphasizes the systems integration scope rather than itemizing specific fastening or coupling materials. Geographic visibility under this code is minimal in current state and local records, and no recent opportunities explicitly solicit sellers coupling as a primary procurement focus.
