Master chart
474 alphabetized part-number rows in the current rich dataset.
This Unicel cross reference chart maps each canonical Unicel cartridge to its Pleatco and Filbur equivalent, verified dimensions, and replacement record. The guide organizes cartridges into series by outside diameter: its 2000 series covers cartridges from 2 through 2.99 inches, while the 9000 series begins at 9 inches. Within a series, the source orders records by diameter and length, then distinguishes them by end-cap details, pleats, media, and OEM references. Use the navigation below to move from that source grouping to the relevant series chart.
The current chart contains 474 rows, with a verification mix of 131 verified-3, 203 verified-2, 140 single-source. These labels describe how many parsed sources represent a cartridge; they do not replace a physical fit check. The rows carry 236 field-level conflict flags where source values cross the published checks. Read the methodology for those rules, and use the measurement guide when a printed number is incomplete or unreadable.
