Rheem-Ruud 43-25135-18 35/5 MFD 440V Oval Dual Run Capacitor

The Rheem-Ruud 43-25135-18 is a dual run capacitor rated at 35/5 MFD (microfarads) and 440 volts, designed for use in HVAC systems. Dual run capacitors serve two motor circuits simultaneously — typically the compressor and the condenser fan motor — making them a compact and reliable alternative to using two separate capacitors.

This oval-style capacitor is a genuine Rheem-Ruud OEM replacement part, engineered to meet the original equipment specifications for compatible Rheem and Ruud heating and cooling systems. Proper capacitance is critical to motor starting and running performance, and using the correct OEM-rated capacitor helps ensure efficient, reliable operation and protects system components from premature wear.
