Darlly 70408 FC-1228 C-7442 PA40 Filter Cartridge is a replacement spa or pool cartridge intended for systems that use the listed cross-reference numbers shown in the product name. This cartridge is a practical option when the existing filter is worn, stained, collapsed, or no longer cleaning water as effectively as it should. The multiple reference numbers in the title help customers compare against the label on their current cartridge, the spa manual, or the filter housing before ordering. Replacing a tired cartridge helps improve circulation, reduce strain on the pump, and support clearer water by capturing debris as water passes through the pleated media.

Because cartridge dimensions and end-cap styles can vary by application, always match the model numbers and physical size before installation. This item is especially useful for service departments, spa owners, and pool owners who need a dependable replacement without guessing from appearance alone.

  • Fits applications matching the listed Darlly and cross-reference cartridge numbers.
  • Helps restore water flow when the old cartridge is clogged or damaged.
  • Useful for spa, hot tub, and pool systems that rely on cartridge filtration.
  • Compare length, diameter, end caps, and reference numbers before ordering.
  • Part number/reference: see product title.
