- It says catalog size disagreements beyond a small tolerance are excluded rather than resolved by guessing.
Field notes
Search can start with a part number or tub brand; when the label is missing, the page accepts diameter and length, with a measurement note specifying end cap to end cap and excluding handles or threads. The site says its cross-references come from Pleatco, Unicel, and Filbur catalogs, links to exact PDF pages, and omits matches when catalog sizes differ beyond a small tolerance. Its listed data-check date is 2026-10-21.
