End-cap geometry and the number/position of O-rings block interchange even when OD and length match — visually compare end caps before fitting, especially with aftermarket cartridges.

Frequently asked questions

What are the dimensions of the RL-035-L-20-B filter element?

The published envelope is 99 mm OD × 156 mm length with a 48.5 mm inside diameter (3.898 × 6.142 in × 1.909 in ID). Confirm against the housing drawing before ordering.

What replaces the RL-035-L-20-B filter element?

1 catalog-confirmed full match(es) (RMR438L20B); 4 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.

These 9 catalog element(s) share the 99×156 mm envelope. Envelope match alone does not guarantee interchangeability — compare micron/Beta, seals and collapse rating.
