Maxitrol R5210-512 Spring

The Maxitrol R5210-512 Blue Spring is a precision-engineered OEM replacement spring designed specifically for Maxitrol RV52, R500, and R500S series regulators. This spring is calibrated to provide an adjustable outlet pressure range of 5-12 inches Water Column (W.C.), ensuring stable performance across residential and light commercial gas appliance applications. As a veteran-grade gas regulator part, the R5210-512 allows technicians to fine-tune gas valve response and maintain consistent downstream pressure essential for high-efficiency burner operation.

Manufactured from high-tensile materials, this Maxitrol replacement spring is color-coded blue for immediate identification during field service. It is compatible with straight-thru-flow (STF) regulators, which are known for their non-lockup design and superior capacity at low inlet pressures. By utilizing the Maxitrol R5210-512, contractors can achieve accurate, sensitive regulation even in demanding environments where precise WC pressure settings are critical for equipment safety and performance.

• Precise Pressure Control: Supports a specific 5-12" WC range, ideal for applications requiring higher manifold pressures within the RV52 and R500 series.
• Application Compatibility: Direct fit for Maxitrol R500S, R500, and RV52 gas regulators, eliminating guesswork during maintenance.
• Color-Coded Identification: The blue spring designation ensures the correct pressure rating is selected at a glance, reducing installation errors.
