Choose the brand printed on the cartridge. Every table leads to a full record with source values, fitments, and conflict flags.
How the charts are organized
Records are keyed on Unicel part numbers because the Unicel catalog provides the most systematic primary structure. Its charts follow the guide’s own outside-diameter series, while the Pleatco and Filbur charts each use one alphabetical table with letter jump links.
Unicel diameter series
Unicel records are paginated by series to keep each master chart compact and directly linkable.
