Sensus 143-62-021-22 Spring

The Sensus 143-62-021-22 Spring is a critical OEM replacement part engineered for the Sensus 143-80 series domestic service regulators. This black/white color-coded spring provides a precise outlet pressure range of 0.5 to 2 PSIG, making it essential for natural gas and propane applications requiring intermediate pressure control in residential or small commercial settings. As a genuine Sensus gas division component, it ensures the internal orifice maintains steady downstream pressure despite fluctuating inlet conditions.

Designed for professional HVAC maintenance and field repair, this spring is compatible with 143-80-1, 143-80-2, and 143-80-6 regulator models. Its technical specifications are calibrated to work with the regulator's 26-square-inch diaphragm assembly, facilitating accurate lock-up and consistent flow rates. Using genuine Sensus parts prevents the common calibration issues associated with aftermarket components, ensuring your gas pressure regulation meets exact safety and performance standards on the job site.

Key Benefits:

• Precise Pressure Range: Specifically calibrated for 1/2 to 2 PSI regulation.
• Model Compatibility: Directly fits Sensus 143-80 series gas regulators used in domestic and light industrial service.
• Visual Identification: Black and White color coding allows for rapid verification of spring range in the field.
• Optimized Performance: Maintains the internal relief valve (IRV) setting accuracy and overall regulator stability.

Common Questions:

Can I use this spring to convert a low-pressure regulator to 2 PSIG?
Yes, replacing a lower-rated spring (such as a blue or green spring) with this 143-62-021-22 black/white spring allows the 143-80 regulator to reach an outlet range of 0.5 to 2 PSIG, provided the inlet pressure and orifice size are within the manufacturer's performance curve.

Is this compatible with Rockwell or Equimeter regulators?
Yes. Because Sensus was formerly known as Rockwell-Equimeter, this part is the direct OEM replacement for older Rockwell 143-80 units.

What happens if I use the wrong spring color?
Using an incorrect spring will lead to improper outlet pressure, potentially causing appliance failure or tripping safety shut-offs. Always verify the part number 143-62-021-22 against the Sensus spring chart before installation.
