Maxitrol R11110-38 Spring

The Maxitrol R11110-38 is a heavy-duty pink replacement spring specifically engineered for precise pressure regulation within RV110, RV111, and 210G series gas regulators. Designed for professional HVACR contractors, this component provides a calibrated 3-8" water column (WC) outlet pressure range, making it essential for mid-range gas manifold adjustments. When performing a regulator spring conversion, the R11110-38 ensures the steady delivery of natural or LP gas to high-demand appliances. Its precision-wound construction maintains consistent tension over prolonged operational cycles, preventing pressure drift and downstream fluctuations. This Maxitrol spring is the standard specification for maintaining gas pressure regulator setpoints in commercial and industrial combustion systems. Proper installation requires matching this spring to the specific vent protector and diaphragm assembly of the host regulator to ensure system integrity and optimal flow rates across the internal orifice.

• Specifically calibrated for 3-8" WC adjustment within RV110, RV111, and 210G series footprints.
• Color-coded pink spring design allows for rapid field identification during manifold service.
• Maintains tight tolerances for gas pressure outlet stability under varying inlet pressures.
• Direct OEM replacement ensures mechanical compatibility with original Maxitrol regulator housings.

What is the pressure range for the Maxitrol R11110-38?
This spring is rated for 3" to 8" water column (WC). If your application requires a lower or higher setpoint, you must select a different color-coded spring compatible with the RV110/RV111 series.

Will this spring work with both Natural Gas and Propane applications?
Yes, provided the regulator body is rated for the fuel type. The spring determines the mechanical tension on the diaphragm to set the outlet pressure regardless of gas density.

How do I identify this spring in an existing regulator?
The R11110-38 is identified by its pink coating. Always verify the spring color and dimensions against the manufacturer’s specification sheet for the RV110 or 210G series before installation.
