Stem Assembly with Cartridge, RP25513

The Delta RP25513 Stem Assembly with Cartridge is a factory replacement part engineered to restore full control and eliminate leaks in Delta two-handle kitchen and lavatory faucets. This complete stem unit includes the cartridge assembly integrated into the stem body, delivering a direct-fit solution that reinstates original hot and cold water regulation. Built by Delta, this stem assembly ensures compatibility with the faucet models it was designed to serve, making it the go-to replacement when aftermarket parts fail to hold up.

• Complete Stem and Cartridge Assembly: This part ships as a single unit with the cartridge already seated inside the stem housing, eliminating the need to source and install components separately. You save time and avoid the trial-and-error of mixing parts from different manufacturers.
• Factory Delta Engineering: Manufactured by Delta to original equipment specifications, this stem assembly guarantees the precise fit and materials that Delta faucets require. You restore the reliability and performance that came with your faucet when it was new.
• Leak Elimination: The integrated cartridge design provides a tight seal that stops drips at the handle and prevents water waste. You regain control over water flow and temperature without the frustration of persistent leaks.
• Direct Replacement for RP25513-3: This part supersedes the earlier RP25513-3 model number, ensuring you receive the current version of the stem assembly. You can order with confidence knowing this is the updated replacement Delta specifies.

The RP25513 stem assembly is designed for use in Delta two-handle faucets installed in kitchens and bathrooms. This part fits specific Delta faucet models that originally shipped with this stem configuration. Before ordering, verify your faucet model number or remove the existing stem to confirm the design matches the RP25513 assembly.

Installation requires removing the faucet handle, unscrewing the retaining nut that holds the old stem in place, and pulling the worn stem assembly from the valve body. Insert the new RP25513 stem assembly into the valve opening, secure it with the retaining nut, and reattach the handle. No ongoing maintenance is required once installed, though periodic inspection of the seats and springs (sold separately as Delta RP4993) can extend the life of the assembly.
