Frequently asked questions

What are the dimensions of the NR-630-E-25-V filter element?

The published envelope is 139.5 mm OD × 399 mm length with a 70.3 mm inside diameter (5.492 × 15.709 in × 2.768 in ID). Confirm against the housing drawing before ordering.

What replaces the NR-630-E-25-V 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.
