Maxitrol R325C10-1022 Red Spring

The Maxitrol R325C10-1022 Red Spring is a factory-calibrated pressure adjustment component engineered for field technicians managing high-capacity gas systems. This red replacement spring is critical for converting or recalibrating Maxitrol 325-3 Series and 220 Series gas regulators to meet specific manifold pressure requirements. Designed to handle outlet pressure ranges from 10–22" W.C. in 325-3 models and 1–3 PSI in 220 Series pilot-loaded regulators, it provides the precise tension necessary for lock-up type regulation in residential, commercial, and industrial 2-PSI piping systems.

Constructed for durability and easy inventory identification, this OEM Maxitrol spring ensures reliable gas pressure control for furnaces, boilers, and industrial ovens. It is fully compatible with Maxitrol 220D, 220E, 220G, and 220J servo-operated models, allowing for accurate proportional adjustments to the pilot regulator. For contractors performing regulator spring kit swaps, the R325C10-1022 maintains system efficiency by preventing pressure fluctuations and ensuring stable dead-end lock-up performance under varying load conditions.

Key Benefits:

• Precise Pressure Calibration: Delivers technical accuracy for 10-22" W.C. and 1-3 PSI applications.
• High Compatibility: Direct fit for 325-3 appliance regulators and the entire 220 Series pilot-loaded line.
• Technician-Friendly Design: Red-tagged finish allows for immediate identification in the field, reducing installation errors.
• Optimized System Safety: Supports consistent gas flow regulation to protect downstream gas-fired equipment.
• Industrial Grade Reliability: Built to withstand the demands of heavy-duty HVACR and plumbing environments.

Common Questions:

Can this spring be used to convert a regulator from Natural Gas (NG) to Liquid Propane (LP)?
Yes, this red spring is frequently used by technicians to achieve the higher manifold pressures required for LP systems, provided the regulator body itself is rated for the specific gas type and inlet pressure.

Is the R325C10-1022 compatible with the 325-5 or 325-7 series?
No, this specific spring is sized for the 325-3 series and the 220 series. Larger regulators like the 325-5 or 325-7 utilize different spring geometries (such as the R325E or R325G series) and are not interchangeable with this model.

Does this spring require a specific mounting orientation?
While the spring functions within the regulator housing, Maxitrol regulators themselves must be installed in an upright horizontal position to ensure the spring tension and vent limiting devices operate according to factory specifications.
