Fitment first
Know it fits before you order.
Wrong-fit returns are the most common problem with replacement cartridges. Meridian publishes complete cross-reference and dimensional data for every part we carry, so you can check yours against ours before ordering.
Fitment data
Cross-reference
Replacement for the Pentair Clean & Clear Plus 320 (CCP320). The system takes four cartridges. If your old element measures 20 in long and 7 in across with 3 in openings at both ends, this is the part.
No legible label? Measure it instead: length, outside diameter, and the openings at each end.
