A.J. Antunes 8101111202 High Gas Pressure Switch Open 2-20" WC M/R 1/4" NPT

The A.J. Antunes 8101111202 High Gas Pressure Switch is used to protect HVAC systems through monitoring of gas pressure. Serving as a safety part, it conducts electrical circuit when the pressure of the gas goes high than the standard pressure of 2/20”WC. This action stops the flow of the gas, avoiding possible deformation of burners, heat exchangers in furnace, boilers, and other gas based HVAC equipment. This switch has a 1/4” NPT connection for easy installation and a manual reset type to guarantee protection against overpressure conditions and avoid expensive repairs for HVAC systems.
