# US Seal RD-25-370 Run Capacitor – 25 MFD 370VAC ### Keep Pool & Spa Motors Running Smoothly and Efficiently A motor run capacitor is essential for maintaining steady, efficient operation after a motor starts. The **US Seal RD-25-370 Motor Run Capacitor** is designed to support continuous operation in pool pumps, spa motors, and blowers by delivering stable electrical capacitance throughout the motor’s run cycle. Rated at **25 MFD and 370VAC**, this OEM-grade capacitor helps motors run cooler, quieter, and more efficiently. When a run capacitor weakens or fails, motors may overheat, lose efficiency, or shut down unexpectedly. Replacing it with the correct capacitor protects your equipment and helps prevent premature motor failure. * * * ### Engineered for Pool & Spa Motor Duty Cycles Pool and spa motors often operate for extended periods in warm, demanding environments. The US Seal RD-25-370 motor run capacitor is built specifically for these conditions, offering consistent electrical performance and moisture-resistant construction suitable for outdoor pool equipment. This capacitor is commonly used in **single-phase pool pump motors**, spa motors, and blowers that require a **25 MFD run capacitor rated at 370VAC**. * * * ### Why the Correct Run Capacitor Matters Motor run capacitors directly affect how efficiently a motor operates during normal use. An incorrect or failing capacitor can increase electrical draw, reduce flow, and shorten motor life. **Why it matters:** - Helps motors run cooler and more efficiently - Reduces electrical stress during extended run times - Prevents unexpected shutdowns and overheating - Extends the service life of pool and spa motors * * * ### OEM-Grade Quality from US Seal US Seal is a trusted manufacturer of pool equipment components, known for producing durable, precision-built electrical parts. The **RD-25-370 motor run capacitor** is manufactured to OEM specifications, ensuring consistent capacitance output and long-term reliability in pool and spa applications. This makes it a dependable replacement for both service professionals and pool owners performing maintenance or repairs. * * * ### Compatibility & Common Applications The US Seal RD-25-370 motor run capacitor is commonly used in: - Residential pool pump motors - Spa and hot tub motors - Pool and spa blowers - Single-phase electric motors requiring a 25 MFD, 370VAC run capacitor Always confirm your motor’s required capacitance and voltage rating before installation. * * * ### Installation Notes Power must be fully disconnected before servicing any motor or capacitor. Motor run capacitors store electrical energy and should be handled with care. If you are unsure about diagnosing capacitor issues or selecting the correct replacement, professional installation is recommended. * * * ### Product Specifications Specification Details Product Name US Seal RD-25-370 Motor Run Capacitor Capacitance 25 MFD Voltage Rating 370 VAC Capacitor Type Motor Run Capacitor Application Pool pumps, spa motors, blowers Motor Type Single-phase Brand US Seal MPN RD-25-370 * * * ### Buy with Confidence from Benchmark Pool Supply When you purchase the **US Seal RD-25-370 Motor Run Capacitor** from Benchmark Pool Supply, you’re buying from a local pool equipment expert who understands real-world pool and spa repairs.
