Frequently asked questions

What are the dimensions of the SE-125-S-50-B filter element?

The published envelope is 69 mm OD × 356 mm length with a 34.2 mm inside diameter (2.717 × 14.016 in × 1.346 in ID). Confirm against the housing drawing before ordering.

What replaces the SE-125-S-50-B filter element?

5 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.
