Full Product Description +

The Polaris K5 Blue Top is a genuine OEM upper housing designed specifically for the Polaris 280 pressure-side pool cleaner. This component forms the outer shell of the cleaner, protecting internal drive components while maintaining proper water flow, hose routing, and overall structural integrity.

Over time, the top housing can crack, fade, or weaken due to UV exposure, impacts, or long-term use. Replacing the blue top restores the cleaner’s original fit, appearance, and protection—without compromising performance.


Why This Part Matters

  • Protects internal gears, jets, and drive components

  • Maintains proper hose and feed line alignment

  • Restores structural rigidity to the cleaner body

  • Prevents water intrusion and debris damage

  • Keeps the cleaner operating at factory specifications


Designed Specifically for Polaris 280 Compatibility

This blue top is molded to Polaris OEM specifications, ensuring precise alignment with mounting points, internal channels, and accessory attachments on the Polaris 280. Using genuine Polaris housing components prevents fitment issues and avoids stress on internal parts caused by aftermarket shells.

This part is not universal and is intended only for compatible Polaris 280 units.


Ideal for Rebuilds, Cosmetic Restoration, and Structural Repairs

The K5 Blue Top is commonly replaced during full Polaris 280 rebuilds or when the cleaner has suffered impact damage or long-term sun exposure. It is also ideal for restoring heavily worn cleaners that are mechanically sound but structurally compromised.

Installation requires partial cleaner disassembly and is recommended for technicians or experienced DIY pool owners.
