Sensus 071-03409-003 Red Spring

The Sensus 071-03409-003 Red Spring is the specified OEM replacement part for technicians maintaining Sensus 496 gas regulators. Designed specifically for high-precision gas pressure regulation, this spring provides a calibrated outlet pressure range of 12 to 28 inches Water Column (WC). Field performance depends on the integrity of the regulator spring to counteract the diaphragm assembly, ensuring stable downstream delivery in residential and light commercial settings. When troubleshooting Sensus 496 regulators for pressure fluctuations or set-point drift, replacing the 071-03409-003 red spring restores the mechanical accuracy required for safe combustion. Built to rigorous Sensus Gas Division specifications, this component resists fatigue in high-cycle environments, making it a critical stock item for gas utility service trucks and industrial gas contractors managing low pressure gas systems.

Technical Benefits for Contractors

• Precise Pressure Control: Specifically engineered for the 12-28" WC pressure range, providing the tension required for accurate set-point maintenance in 496 models.
• Direct OEM Fitment: Eliminates the risks associated with generic springs, ensuring the Sensus 496 regulator maintains its original domestic or commercial certification.
• Durable Material Composition: High-tensile alloy construction designed to withstand environmental stressors and constant mechanical compression.
• Simplified Serviceability: Standardized Sensus 071-03409-003 dimensions allow for rapid field replacement during routine regulator teardowns.

Common Questions

What is the color code for Sensus 496 springs?
The red color code on part 071-03409-003 specifically designates the 12 to 28" WC range. Using a spring with an incorrect color code will result in improper outlet pressure and potential safety hazards.

Can this spring be used in other Sensus regulator models?
While some Sensus components share characteristics, this red spring is optimized for the Sensus 496 domestic service regulator. Always verify your specific orifice size and inlet pressure against the manufacturer’s spring selection chart.

When should a regulator spring be replaced?
Replace the gas regulator spring if you detect permanent set (loss of free length), corrosion, or if the regulator fails to maintain the desired outlet pressure under flow conditions.
