Frequently asked questions

What are the dimensions of the RHR660A03B filter element?

The published envelope is 95.5 mm OD × 333 mm length with a 68.5 mm inside diameter (3.760 × 13.110 in × 2.697 in ID). Confirm against the housing drawing before ordering.

What replaces the RHR660A03B filter element?

2 catalog-confirmed full match(es) (RE-160-A-03-B, RE160A03B4)

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.
