Maxitrol R11110-13 Spring

The Maxitrol R11110-13 is a precision-engineered brown spring specifically designed for RV110, RV111, and 210G series gas pressure regulators. As a veteran technician knows, maintaining the correct outlet pressure is critical for appliance efficiency and safety. This replacement regulator spring provides a specific outlet pressure range of 1.0" to 3.5" W.C., making it the standard choice for low-pressure natural gas or propane applications where tight manifold pressure control is required. Built with high-tensile stainless steel, the R11110-13 resists mechanical fatigue and corrosion in demanding boiler and furnace environments. Its physical dimensions—approximately 1.5 inches in diameter and 6.125 inches in length—ensure a proper fit within the regulator adjustment stack. When performing a Maxitrol spring replacement, ensure the gas supply is shut off and the seal cap is removed before adjusting the screw to compress the new spring to your required set point.

• Precise Pressure Regulation: Delivers a consistent 1.0-3.5" W.C. range for RV110, RV111, and 210G regulators.
• Industrial-Grade Durability: Constructed from corrosion-resistant materials to ensure long-term stability in HVACR systems.
• OEM Compatibility: Guaranteed fit for Maxitrol 210G series units, eliminating the risks associated with generic aftermarket springs.
• Color-Coded Identification: The brown spring designation allows for quick visual verification of the pressure rating during field service.

Can I use this spring in an RV47 or RV48 regulator?
No, the R11110-13 is sized specifically for the larger RV110/111 and 210 series housings. Always verify your regulator model number before installation.

How do I identify if this is the correct spring for my manifold pressure?
The brown color indicates a 1-3.5" W.C. range. If your application requires a higher pressure (e.g., 3-8" W.C.), you will need a different color-coded spring, such as the pink variant.

Does this spring work for both Natural Gas and LP?
Yes, provided the required outlet pressure falls within the 1.0" to 3.5" W.C. range, it is compatible with both fuel types in the supported regulator series.
