Description
The A.J. Antunes 8104116304 is an OEM low pressure gas switch used to monitor and control gas pressure in commercial gas fired equipment and HVAC systems. It is part of Antunes’ Model G series of switches (often designated RLGP G), engineered to provide automatic reset functionality and reliable pressure sensing at a defined range. This pressure switch opens or interrupts an electrical control circuit when the monitored gas pressure falls below or rises above a set threshold, helping maintain safe operation of burners and combustion systems. It connects via a 1/4″ NPT threaded port and is designed for compatibility with a wide range of commercial appliances such as ovens, fryers, steamers, and other equipment requiring regulated gas pressure monitoring.
