D172G25A filter element: specifications & equivalents

Q: What are the dimensions of the D172G25A filter element?

The published envelope is 76 mm OD × 426 mm length with a 38.2 mm inside diameter (2.992 × 16.772 in × 1.504 in ID). Confirm against the housing drawing before ordering.

Q: What micron rating does D172G25A 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 D172G25A is a Filtrec inline-line hydraulic filter element, built with glassfiber media, sized 76 × 426 mm OD × length (ID 38.2 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 D172G25A filter element?

The published envelope is 76 mm OD × 426 mm length with a 38.2 mm inside diameter (2.992 × 16.772 in × 1.504 in ID). Confirm against the housing drawing before ordering.

What micron rating does D172G25A 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 D172G25A filter element?

4 catalog-confirmed full match(es) (11616D25BN, F820016K25B, P174548…); 1 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.
