UNSPSC 40142710: Flange compact/hub clamp all material

A compact flange or hub clamp is a type of flange that uses a different design from traditional flanges to create a stronger and more reliable connection between two pipes or other equipment. Instead of using bolts and nuts to hold the flange in place, a compact flange or hub clamp relies on a pre-loaded tapered plug that is compressed between the flange faces to create a leak-proof seal.

Pipe compact flange /hub clamp made of carbon steel, high yield carbon steel, alloy steel, stainless steel, duplex and super duplex, and various nickel alloy grades such as Inconel, Incoloy, Hastelloy, and Monel etc.

UNSPSC 40142710 Flange compact/hub clamp all material, a Commodity code, does not align with the recent state and local procurement activity tagged under it. The single recent opportunity in the dataset — City of Jackson DPW Ready-Mix Concrete (RFP 2026PUBLICWORKS021, response due June 18, 2026) — solicits ready-mix concrete delivery services, batch materials, aggregates, and concrete accessories for construction and emergency repair work. This scope bears no relationship to flange clamps, compact hubs, or related mechanical fastening or coupling components that the code nominally describes. The mismatch suggests the opportunity was miscoded by the issuing body or the data aggregator.

The code shows little relevant recent activity in state and local procurement. No additional opportunities aligned with the nominal scope of flanged hubs or clamp assemblies appear in the available records. Bidders tracking this code for mechanical or structural clamping applications should monitor for future opportunities but should not rely on the current activity as an indicator of genuine demand under this Commodity classification.
