Sensus 143-62-021-18 Orange Spring

Ensure field-level accuracy in gas pressure regulation with the Sensus 143-62-021-18 Orange Spring. This legitimate OEM replacement component is engineered specifically for the Sensus 143-80 gas regulator series, providing a calibrated 12-28" WC outlet pressure range. In the world of industrial and commercial gas service, maintaining the correct water column is critical for downstream equipment performance and system stability. Whether you are servicing a standard 143-80-1 or an internal relief 143-80-2 model, this orange main spring provides the high-tensile reliability required for natural gas, propane, and air applications.

A veteran tech knows that any drift in gas regulator replacement springs can compromise the combustion efficiency of boilers, furnaces, and unit heaters. That is why the 143-62-021-18 is manufactured to precise tolerances, preventing excessive pressure droop and ensuring consistent flow across varying inlet pressures (up to 60-125 PSIG depending on orifice size). This spring is the standard choice for contractors upgrading residential service regulators to higher pressure commercial requirements.

• OEM Compatibility: Exact fit for Sensus-Gas Division 143-80, 143-80-1, and 143-80-2 model regulators.
• Calibrated Range: Provides a stable 12" to 28" water column (WC) adjustment window for mid-pressure applications.
• Superior Construction: Die-cast and treated materials prevent fatigue and maintain set-point accuracy in temperatures from -20°F to 150°F.
• Versatile Media: Approved for use with natural gas, LP gas, nitrogen, and dry CO2.

Can this spring be used to convert a low-pressure regulator?
Yes, by replacing a green or blue spring with this orange 143-62-021-18 spring, a technician can increase the outlet pressure range of a standard 143-80 regulator to the 12-28" WC bracket.

How do I adjust the pressure once the spring is installed?
After installation, remove the regulator cap and turn the adjustment button clockwise to increase the outlet pressure or counter-clockwise to decrease it. Always perform adjustments while gas is flowing through the unit for an accurate reading.

Does this fit the 143-80-2HP high-pressure models?
While compatible with the 143-80 series, high-pressure "HP" models often utilize different spring configurations for PSI-level output. Verify your specific manifold requirements before installation.
