Maxitrol R325E10-711A Spring

The Maxitrol R325E10-711A is a precision-engineered white spring designed specifically for the 325-5 series regulators. Primarily used in pounds-to-inches gas regulation, this component allows for field adjustment of the outlet pressure within a 7-11" WC (Water Column) range. For HVAC contractors and gas technicians, this spring is essential when converting or fine-tuning Maxitrol 325-5A or 325-5B appliance gas regulators for high-efficiency residential, commercial, or industrial service.

Constructed from high-tensile, rust-resistant materials, this heavy-duty spring ensures consistent positive dead-end lockup and precise pressure modulation from full flow down to pilot flow. It is compatible with a wide variety of fuel sources, including natural gas, LP gas-air mixtures, and liquefied petroleum gases. Its distinct white color-coding allows for immediate identification in the field, preventing calibration errors during pressure regulator maintenance. When working with 2 PSI or 5 PSI piping systems, utilizing the correct Maxitrol spring range is critical to maintaining the safe and efficient operation of downstream appliance controls.

• Precise Pressure Control: Specifically calibrated to maintain a stable 7-11" WC outlet pressure for 325-5 series units.
• Broad Compatibility: Fully compatible with Maxitrol 325-5A and Imblue-coated 325-5B regulators.
• Field Reliability: Durable, fatigue-resistant design prevents pressure drift in demanding industrial gas regulation environments.
• Easy Identification: White color-coded finish ensures the correct spring is used for the specified inches water column requirement.

Is the R325E10-711A compatible with the smaller 325-3 series?
No, this spring is specifically sized for the 325-5 series. Using this in a 325-3 or 325-7 series regulator will result in improper seating and inaccurate pressure regulation.

What is the purpose of the white color coding?
Maxitrol utilizes color-coded springs to denote specific outlet pressure ranges. The white spring indicates a 7-11" WC range, as opposed to the violet (4-12" WC) or red (10-22" WC) options.

Can this spring be used for outdoor regulator applications?
Yes, when installed within a 325-5B regulator featuring Imblue Technology, the Maxitrol R325E10-711A is suitable for outdoor environments, provided the vent is properly protected.
