Maxitrol R325C10-P12 Tagged Spring

The Maxitrol R325C10-P12 Tagged Spring is a critical component for technicians calibrating 325-3 Series regulators to a specific 1-2 PSI outlet pressure. Engineered for precise pressure control, this OEM spring provides a high-tension range of 20" to 42" W.C., making it essential for 2 PSI piping systems and high-demand gas appliance loads. As a veteran HVACR professional, you know that maintaining the correct spring tension is non-negotiable for positive dead-end lockup and stable downstream flow across natural gas or LP applications.

Replacing a standard spring with this tagged gas regulator spring allows for consistent delivery in industrial gas pressure regulation and commercial boiler feeds. The R325C10-P12 is specifically color-coded or tagged for immediate field identification, ensuring you aren't guessing at the pressure range during a service call. This Maxitrol replacement part is built for durability in demanding environments, supporting the 325-3's lever-acting design and multi-positional mounting capabilities when used without a vent limiter.

• Precise 1-2 PSI Range: Provides a stable 20-42" W.C. outlet pressure for high-pressure residential and commercial loops.
• OEM Compatibility: Exact fit for all Maxitrol 325-3 Series models, ensuring factory-spec performance.
• Easy Identification: Clearly tagged to prevent installation errors and ensure the correct spring selection for the job.
• Application Versatility: Suitable for use with natural, manufactured, mixed, and liquefied petroleum gases.
• Reliable Lockup: Supports the regulator's ability to maintain control from full flow down to pilot flow.

Can this spring be used in a 325-5 or 325-7 series regulator?
No, the R325C10-P12 is specifically sized and tensioned for 325-3 Series regulators. Using it in larger housings will result in improper pressure regulation and potential system failure.

Does the 1-2 PSI spring require a specific mounting position?
While the spring itself is multi-positional, the Maxitrol 325-3 regulator must be mounted in an upright horizontal position if a vent limiting device is installed. Always verify the flow arrow on the casting during installation.

Is this the correct spring for a 2 PSI line pressure system?
Yes, this spring is the industry standard for converting or maintaining 325-3 regulators within a 2 PSI gas piping system where a higher manifold pressure is required before the final appliance regulator.
