Ensure reliable pressure regulation in commercial gas services with the Sensus 143-82-021-00 Red and Black Spring. Specifically engineered for the Sensus 243-8 service regulator, this main adjustment spring provides a precise outlet pressure range of 3.5" to 6.5" w.c. (water column). As a critical component in Sensus 243-8-2 and 243-12 series valve bodies, this OEM regulator spring allows technicians to dial in set-points for boilers, industrial furnaces, and large-scale commercial water heaters. The red/black color coding ensures fast identification during field maintenance or multi-stage pressure swaps. Manufactured from high-tensile steel, this commercial gas regulator spring maintains its rate and calibration under heavy cycles. Whether you are performing a seasonal tune-up or reconfiguring a Sensus gas regulator for natural gas or propane applications, utilizing genuine 143-82-021-00 hardware prevents outlet pressure drift and ensures downstream appliance safety. Key Benefits Precise Calibration: Provides a stable 3.5" to 6.5" w.c. range, ideal for standard low-pressure commercial burner manifolds. OEM Compatibility: Exact fit for Sensus 243-8 Model industrial regulators, ensuring seamless integration with existing diaphragm-case assemblies. Reliable Performance: Heavy-duty construction resists fatigue and maintains set-point accuracy across a wide range of flow rates. Simplified Maintenance: The red and black color code allows for rapid visual verification of pressure capabilities without specialized tools. Common Questions Can I use this spring in the Sensus 243-12 regulator? This specific part number (143-82-021-00) is the standard red/black spring for the 243-8 series. While many Sensus bodies are interchangeable, always verify the specific orifice and diaphragm size before installation. What happens if I need a higher pressure range? If your application requires a range above 6.5" w.c., you must swap to a different color-coded spring, such as the blue/black (5" - 8.5") or green/black (6" - 14"), to ensure the regulator operates within its design parameters. Is this spring compatible with both natural gas and LPG? Yes, the spring provides the physical force required to regulate any compatible inert gas used within the Sensus 243-8 service regulator body.
