Frequently asked questions

What are the dimensions of the SD-125-F-20-B filter element?
The published envelope is 79.8 mm OD × 333 mm length with a 40.2 mm inside diameter (3.142 × 13.110 in × 1.583 in ID). Confirm against the housing drawing before ordering.
What replaces the SD-125-F-20-B filter element?
2 partial match(es) requiring parameter review
Is a same-envelope aftermarket element always a drop-in replacement?
No. Matching OD and length only proves the cartridge fits the bowl. End-cap style, seal compound, micron/Beta rating, collapse pressure and bypass configuration must also match; the table above tags every equivalent as full, partial or verify for exactly this reason.
