Maxitrol R5310-38 Spring

The Maxitrol R5310-38 is a 3-8" WC pink spring engineered specifically for technical precision within Maxitrol RV53, R600, and R600S series gas pressure regulators. This OEM replacement spring is critical for technicians performing manifold pressure adjustments on straight-thru-flow (S-T-F) regulators used in residential and commercial boiler systems. By replacing a fatigued or incorrect spring with this authentic Maxitrol part, contractors ensure stable outlet pressure and prevent common issues like hunting or erratic gas flow. The color-coded pink spring allows for rapid field identification during routine maintenance or high-demand heating season calls. Optimized for both natural gas and LP applications, the R5310-38 provides the necessary tension to maintain the specific 3 to 8 inches of water column range required for mid-range appliance input requirements. Rely on this gas regulator accessory to restore factory-spec performance to your Maxitrol gas controls while ensuring compliance with technical pressure drop charts.

• Precise Pressure Control: Maintains a steady 3-8" WC outlet pressure for high-efficiency burners.
• Direct OEM Compatibility: Specifically calibrated for the RV53, R600, and R600S regulator architectures.
• Field Identification: High-visibility pink coating simplifies part identification for service technicians.
• Durable Construction: Engineered to withstand the cyclical stress of light commercial gas demand.

• Can I use this spring in an RV52 regulator? No, the R5310-38 is specifically sized for the larger RV53 and R600 bodies; using it in an RV52 may result in incorrect setpoints.
• How do I fix regulator "hunting" with this spring? First, verify the vent is not obstructed. If the pressure still fluctuates, ensure this 3-8" spring matches your appliance's manifold requirements.
• Is this spring suitable for liquid propane? Yes, provided it is installed in a compatible Maxitrol regulator rated for LP gas mixtures.
