A.J. Antunes 804112101 Auto Reset Gas Pressure Switch 2-16" WC High 1-6" WC Low RHLGPA

The A.J. Antunes 804112101 Gas Pressure Switch, model RHLGPA, is an automatic reset part used to control and signal gas pressure in various HVAC systems. This switch works for high pressure with an operating range of 2-16” WC and for low pressure with an operating range of 1-6” WC, which interrupts the electrical control circuit when the pressure is out of set range. It has a rigid build with 3/8” NPT high-pressure and 1/8” NPT low-pressure fittings for better performance. Standard in most commercial heating systems, this switch increases safety by eliminating the risks of gas leakage and equipment degradation and offers variable positions for optimal performance.
