Bard 9043-085 - Q300A 23 inch thermocouple

Bard part number 9043-085 is a Q300A 23 inch thermocouple used in Bard gas heating sections to prove pilot flame and safely keep the gas valve energized only when a proper flame is present. As the pilot heats the tip, the thermocouple generates a small millivolt signal that helps prevent nuisance shutdowns and supports reliable ignition operation when the pilot assembly and wiring are in good condition. This is a genuine Bard OEM replacement component intended to match original fit, connection, and performance requirements, making it a smart choice when you are troubleshooting weak millivolt output, intermittent pilot dropout, or an aging flame-sensing circuit on compatible Bard equipment.
