different series require different spring diameters and lengths such as the R325 series

typically from -50°F to 300°F

Combustion Optimization: Helps prevent common issues like "lazy flames" or excessive carbon monoxide production by maintaining the correct gas velocity

a 440V capacitor is a safe upgrade for a 370V circuit

As a manual reset limit switch

Sensus 143-62-023-45 Orifice different series require different springThe Sensus 143 62 023 45 Orifice is an essential component for technicians maintaining or configuring the Model 143 80 service regulator. Engineered from high grade aluminum, this 1 2 inch replacement orifice is designed for low pressure applications, typically supporting maximum inlet pressures up to 20 psig. It plays a critical role in managing flow capacity and ensuring stable downstream pressure for residential and small commercial gas systems.
