UNSPSC 31163023: Muff coupling

A type of device that has two shafts to face and fit together within a cast iron or cast steel cylinder and is bound with keys. This device is the simplest coupling to use if the axis diameter and the load for conveyance are very small.

UNSPSC 31163023 Muff coupling is a Commodity code, but the recent state and local opportunities posted under it do not reflect the nominal scope of mechanical coupling hardware. The two most recent solicitations—West Basin Municipal Water District's on-call pump and motor repair contract and DeKalb County's tennis center IT infrastructure project—are unrelated to muff couplings or their procurement. The code shows little relevant recent activity aligned with its stated product line.

No recent opportunities reflect actual demand for muff coupling products or related mechanical coupling services at the state and local level. The misalignment between the code's nominal scope and the work being solicited suggests either a tagging error in the opportunities database or minimal procurement activity under this code in state and local markets during the current cycle.
