Maxitrol R400B10-13 Spring

Adjusting the outlet pressure on your Maxitrol R400 or R400S series gas regulator requires a high-performance spring designed for precision. The Maxitrol R400B10-13 Brown Spring is an essential component for technicians looking to achieve a stable 1 to 3.5 inches Water Column (WC) range. Manufactured from durable, corrosion-resistant materials, this replacement gas regulator spring is engineered to maintain setpoint integrity even under varying inlet pressures, making it ideal for both main burner and pilot load applications.

When performing field conversions or fine-tuning HVAC gas pressure regulation, the color-coded brown finish allows for immediate identification, reducing the risk of incorrect installation. This Maxitrol spring is specifically calibrated for the R400 and R400S residential and industrial appliance regulators, ensuring compatibility with natural, manufactured, mixed, and liquefied petroleum gases. For a veteran contractor, this is the standard choice for reliable gas appliance pressure adjustment in low-pressure systems.

• Precision Control: Optimized for a 1-3.5" W.C. pressure range to ensure stable delivery.
• Direct Compatibility: Specifically engineered for Maxitrol R400 and R400S regulators.
• Color-Coded Identification: Brown spring marking prevents site-installation errors.
• High-Grade Construction: Built for longevity and resistance to internal corrosion.
• Multi-Gas Application: Suitable for systems utilizing Nat, LP, or mixed gas types.

Can this spring be used to convert an R400 or R400S regulator to LP?
Yes, provided the required outlet pressure falls within the 1-3.5" W.C. range. Always verify the specific burner manifold requirements before installation.

Does this spring fit other Maxitrol regulator series?
This specific part number is designed for the R400 and R400S series. Using it in other models like the RV or 325 series will result in inaccurate pressure regulation and potential safety risks.

Is professional installation required for this part?
Yes. All gas pressure adjustments and internal component replacements must be performed by a licensed technician in accordance with local safety codes and manufacturer specifications.
