Frequently asked questions

What are the dimensions of the MD-025-L-20-B filter element?

The published envelope is 70 mm OD × 198 mm length with a 28.5 mm inside diameter (2.756 × 7.795 in × 1.122 in ID). Confirm against the housing drawing before ordering.

What replaces the MD-025-L-20-B filter element?

1 catalog-confirmed full match(es) (D831C25A); 6 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.

These 6 catalog element(s) share the 70×198 mm envelope. Envelope match alone does not guarantee interchangeability — compare micron/Beta, seals and collapse rating.
