R146G25C filter element: specifications & equivalents

Q: What are the dimensions of the R146G25C filter element?

The published envelope is 99 mm OD × 437 mm length with a 51.5 mm inside diameter (3.898 × 17.205 in × 2.028 in ID). Confirm against the housing drawing before ordering.

Q: What micron rating does R146G25C use?

This element is rated 22 µm absolute — β22(c)≥1000. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The R146G25C is a Filtrec inline-line hydraulic filter element, built with glassfiber media, sized 99 × 437 mm OD × length (ID 51.5 mm), rated at 22 µm absolute (β22(c)≥1000). Verify against the current manufacturer data sheet before ordering.

Selection pitfalls — read before you substitute

“10 µm nominal” and “12 µm at β1000” can describe the very same media — one is reported at β≥200, the other at β≥1000 per ISO 16889. Compare ratings at the same Beta test point, not just the printed micron number.

Frequently asked questions

What are the dimensions of the R146G25C filter element?

The published envelope is 99 mm OD × 437 mm length with a 51.5 mm inside diameter (3.898 × 17.205 in × 2.028 in ID). Confirm against the housing drawing before ordering.

What micron rating does R146G25C use?

This element is rated 22 µm absolute — β22(c)≥1000. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

What replaces the R146G25C filter element?

2 catalog-confirmed full match(es) (MF1902A25HBE, MF1902A25HBEP01)

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.
