UNSPSC 31163010: Spider coupling

A connecting device used on shafts of rotary machines to make connections. It is star or spider shaped, elastic but very resistant.

UNSPSC 31163010 Spider coupling is a Commodity code that in recent state and local procurement activity appears to be tagged inconsistently with actual purchasing activity. The recent solicitations posted under this code show little relevant purchasing for spider couplings or mechanical coupling assemblies. Instead, the opportunities reflect broader consumables and parts procurement across telecommunications, HVAC components, janitorial supplies, hardware, audio equipment, and door lock services — none of which align closely with spider coupling sourcing. The Texas Health and Human Services Commission, City of Austin, Hillsborough County Board of County Commissioners, Illinois Department of Corrections, and Donna Independent School District have posted recent solicitations tagged with this code, but the work being bought spans telecom parts, refrigerants and blower motors, janitorial supplies, station alerting audio parts, and door hardware repair services rather than mechanical couplings. This suggests either a tagging or taxonomy-mapping issue at the issuing level rather than active procurement demand for spider couplings.

Recent opportunities show activity concentrated in Texas and Florida jurisdictions, with secondary activity in Illinois, Washington, and Minnesota through cooperative purchasing vehicles such as Sourcewell. The Texas Health and Human Services Commission appears most frequently, with multiple blanket order solicitations for HVAC equipment, telecom parts, and related supplies issued in June and July 2026. Representative examples include HHS0017634 (chemicals, gases, HVAC equipment, and supplies, IFB due July 28, 2026) with an estimated contract value of $50,000, and HHS0017595 (telecom parts and tools, due August 3, 2026). Hillsborough County Fire Rescue sought janitorial and operational supplies under ITB 26-00319 (due July 24, 2026, estimated at $765,679.84), and the City of Austin issued IFB DCG1036 for station alerting audio parts (due July 14, 2026). The Sourcewell RFP #061626 for law enforcement equipment represents a multi-jurisdictional cooperative purchasing effort due June 16, 2026. The code shows no clear pattern of spider coupling procurement and warrants clarification of the actual commodity category mapping before pursuit.
