Hayward Cartridge Element for StarClear C550 Filter | CX550RE

The Hayward Cartridge Element (CX550RE) is the OEM replacement filter cartridge element for the Hayward StarClear C550 cartridge filter. This is the genuine Hayward part, engineered to the exact fit and performance specifications of the original element your C550 shipped with. What It Does The CX550RE element sits inside the StarClear C550 filter tank and captures dirt, debris, and fine particulates as pool water passes through its pleated filter media. Replacing this element on schedule restores the filter's designed flow rate and debris-holding capacity, keeping your water clear without straining your pump. Specifications Hayward Part Number CX550RE Quantity Each (1) Length 19 3/4" Outer Diameter 7" Top Inner Diameter 3" Bottom Inner Diameter 3" Fits Into Brand Equipment Line Model / Part Number Hayward StarClear C550 Compatibility is based on Hayward parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your filter's manual or on the original cartridge before ordering. Poolaroo Pro Tip Before ordering, measure your old element: it should be 19 3/4" long with a 7" outer diameter. If those numbers don't match, double-check your filter model number — the StarClear range spans several tank sizes, each with its own element. When it's time to clean, rinse the pleats with a garden hose working top to bottom; avoid a pressure washer, which can damage the media. For deep-seated sunscreen and body oil buildup, soak the element overnight in a dedicated cartridge filter cleaner before rinsing, and you'll get noticeably more service life between replacements.
