Why Use Genuine OEM Parts?
Using factory-specified replacement springs like the Sensus 143-16-021-04 helps maintain the integrity of your gas regulator’s pressure-setting mechanism. Aftermarket or incorrect springs can alter outlet pressure calibration, leading to unsafe or non-compliant operation. Always specify the correct color-coded spring for your regulator model during service or rebuild procedures.
