Frequently asked questions

What are the dimensions of the SD-010-K-20-B filter element?

The published envelope is 45.5 mm OD × 103 mm length with a 20.5 mm inside diameter (1.791 × 4.055 in × 0.807 in ID). Confirm against the housing drawing before ordering.

What replaces the SD-010-K-20-B filter element?

1 catalog-confirmed full match(es) (D810C25RA); 5 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.
