UNSPSC 40141746: Sight glass

A part mounted to a tank or boiler for observing the content level

UNSPSC 40141746 Sight glass (Commodity) describes components and parts for refrigeration and compressed-air systems, but recent state and local solicitations under this code show minimal alignment with the nominal scope. The posted opportunities center instead on compressor components, school bus air-conditioning systems, ice-maker equipment and cleaning services, foodservice refrigeration repair, and law enforcement equipment—a mismatch that signals the code receives little relevant procurement activity from state and local buyers pursuing sight-glass inventory or components. Of the five recent opportunities tagged to this code, only one—the Illinois Secretary of State's October 2026 RFQ for Quincy compressor components—falls within the refrigeration and compressed-air product family; the others concern repair services and equipment unrelated to sight glass specifically.

The issuing bodies span school districts (Hillsborough County Public Schools, Pinellas County School District), municipal governments (City of Tampa, Illinois Secretary of State), and a university (University of Wisconsin-Madison), with no standout repeat buyers under this code. Geographic activity is concentrated in Florida (Tampa, Hillsborough County, Pinellas County) and Illinois, with a single Wisconsin posting. Representative opportunities include the Illinois Secretary of State's RFQ for Quincy compressor repair components due October 19, 2026, and the Pinellas County School District's RFQ for ice-maker cleaning and sanitation services (121 school locations, approximately $45,000 for the initial one-year term) with a response deadline of April 30, 2026. Given the disconnect between the code's description and actual solicitation scope, pursuing vendors should verify that opportunities posted under this code align with their product or service offering before investing in RFQ or RFP response.
