Product Overview
The Jandy R0515400 Screw With O-Ring plays a crucial role in maintaining the integrity of the pump’s impeller mounting system. Over time, original screws may loosen, the O-ring may degrade, or thread wear may occur, leading to leaks or impeller instability. By installing this factory-specified screw assembly, service technicians and installers restore the correct sealing and secure fit of the impeller hub to pump housing.

Because the screw uses a reverse-thread design, it resists loosening under the rotational forces of high-performance pool pumps. The integrated O-ring simplifies installation and ensures proper sealing without requiring separate gaskets. This component is particularly useful when rebuilding or upgrading pumps across multiple Jandy model lines: ePump, FloPro, Stealth, PlusHP, and others. Including this part in your maintenance kit or inventory supports proactive upkeep and helps ensure consistent pump performance and leak-free operation.
