Frequently asked questions

What are the dimensions of the D921T75A filter element?

The published envelope is 73.6 mm OD × 232 mm length with a 32 mm inside diameter (2.898 × 9.134 in × 1.260 in ID). Confirm against the housing drawing before ordering.

What replaces the D921T75A filter element?

1 catalog-confirmed full match(es) (P174560)

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.
