A.J. Antunes 8103116303 Pressure Switch

The Antunes 8103116303 is a precision-engineered LGP-G Low Gas Pressure Switch designed for critical monitoring of gas pressure levels in commercial burners and HVACR systems. Operating within a set point range of 5-30" W.C., this unit features a Manual Reset mechanism and a Single Pole Double Throw (SPDT) switch configuration, ensuring reliable safety interlocking during low-pressure events. Constructed with a die-cast aluminum housing and a 1/4" NPT connection, it provides high durability and easy integration into existing gas trains. This component serves as the direct 8271003075 replacement, maintaining the exact form, fit, and function for legacy Antunes installations. Contractors can rely on its sensitive diaphragm and snap-action switch for accurate gas pressure monitoring, preventing hazardous conditions by locking out the system until manual intervention occurs. Its modular design allows for upright or side mounting, catering to tight mechanical room clearances.
