Frequently asked questions

What are the dimensions of the RN-030-K-20-B-NB filter element?
The published envelope is 55 mm OD × 168 mm length with a 26 mm inside diameter (2.165 × 6.614 in × 1.024 in ID). Confirm against the housing drawing before ordering.
What replaces the RN-030-K-20-B-NB filter element?
3 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.
