Hayward CX3020DA Top Closure Plate for SwimClear® C3020 / C4020 Series
The Hayward CX3020DA is a replacement top closure plate designed for SwimClear cartridge filters (models C3020, C3025, C4020, C4025). It provides the sealing interface at the top of the filter, securing the cartridge elements and ensuring proper flow through the system.
Key Features

Installation & Compatibility Notes
Before installation, shut off the pump and relieve system pressure. Remove the clamp assembly, lift off the old top plate, and inspect the cartridge elements and seating surface for debris or damage. Install the new CX3020DA plate ensuring the cartridge elements are seated evenly and aligned. Reassemble the clamp system and restore circulation. After startup, monitor pressure and flow to confirm system integrity.
Maintenance Tips
- Inspect the top plate at each service interval for cracks, warping or seal irregularities.
- If you notice bypass flow, rising pressure or misalignment of cartridge elements, replacing the top plate is a recommended corrective step.
- Ensure that the clamp assembly is properly torqued and the O-ring is intact to maintain full seal effectiveness.

For pool service technicians and homeowners maintaining cartridge-style filters, the Hayward CX3020DA top closure plate offers a genuine replacement component that helps restore filter integrity, extend service life of the cartridge elements and maintain proper hydraulic performance.
