Utica-Dunkirk 127000014 Pressure Switch 321042-401 and Intertherm furnace unitsEnsure system safety and operational integrity with the Utica Dunkirk 127000014 High Pressure Switch. This critical safety component is engineered as a manual reset pressure switch, designed to trip and interrupt the heating circuit if internal boiler pressures exceed safe thresholds. Specifically calibrated to opens at 415 PSI, this limit control acts as a terminal failsafe, protecting the heat exchanger and hydronic piping from over pressurization
