Frequently asked questions
What are the dimensions of the RA-1000-E-20-B filter element?
The published envelope is 203 mm OD × 545 mm length with a 157 mm inside diameter (7.992 × 21.457 in × 6.181 in ID). Confirm against the housing drawing before ordering.
What replaces the RA-1000-E-20-B filter element?
1 catalog-confirmed full match(es) (R742G25); 10 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
