Maxitrol R8110-25 Spring

The Maxitrol R8110-25 is a high-performance plated spring specifically designed for use with HVACR line and appliance pressure regulators. Engineered for contractors managing RV81, 210D, and 325-7A Series regulators, this replacement gas regulator spring provides a stable 2-5" w.c. outlet pressure range (water column). Its plated finish ensures long-term resistance to environmental factors, maintaining consistent tension and precise gas pressure regulation in residential, commercial, and industrial boiler or furnace systems. When performing field service or pressure adjustments, technicians rely on the R8110-25 for its exact fit within the Maxitrol spring selection chart specifications. Installing this Maxitrol spring allows for fine-tuned calibration of downstream equipment, ensuring the regulator maintains its lock-up performance and flow stability even under varying inlet pressures. This part is essential for maintaining the integrity of 325 Series pounds to inches regulators and other compatible Maxitrol gas controls.

• Exact Compatibility: Optimized for Maxitrol RV81, 210D, and 325-7A regulator bodies.
• Precision Range: Provides a dependable 2-5" w.c. adjustment window for low-pressure applications.
• Industrial Durability: The plated spring construction prevents corrosion, ensuring reliable mechanical tension.
• Operational Stability: Reduces hunting and improves regulating stability across high-demand heating equipment.

• Which regulators use the R8110-25 spring? This part is the standard 2-5" w.c. spring for the RV81, 210D, and 325-7A series.
• Can I use this spring to change the outlet pressure of my 325-7? Yes, the R8110-25 is used to convert or adjust the regulator's outlet pressure within the 2" to 5" w.c. range.
• How do I identify this spring in the field? Look for the plated finish; Maxitrol uses color-coding or plating (like this one) to distinguish pressure ranges.
