Frequently asked questions

What are the dimensions of the WP341 filter element?

The published envelope is 90 mm OD × 297 mm length with a 41 mm inside diameter (3.543 × 11.693 in × 1.614 in ID). Confirm against the housing drawing before ordering.

What replaces the WP341 filter element?

1 catalog-confirmed full match(es) (PT9148); 1 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.
