Frequently asked questions
What are the dimensions of the RA-450-E-20-B filter element?
The published envelope is 126 mm OD × 390 mm length with a 92 mm inside diameter (4.961 × 15.354 in × 3.622 in ID). Confirm against the housing drawing before ordering.
What replaces the RA-450-E-20-B filter element?
1 catalog-confirmed full match(es) (R733G25); 12 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.
Same-envelope elements from other brands
