Hayward CX900DA Knob Kit Replacement for Hayward Star-Clear Cartridge Filters

CX900DA knob kit

This listing identifies CX900DA as a knob kit replacement for Hayward Star-Clear cartridge filters. It is listed as a knob kit, not a filter element or tank part.

Fit checks

• Confirm your filter is in the Star-Clear family and compare the old knob or part number before ordering.
• Because it is sold as a kit, check whether you need the full set. If the lid seal or tank threads are damaged, a knob alone may not address that problem.

Use your existing hardware to decide if this replacement addresses only missing knobs.
