01.E 90.25VG.HR.E.V.- filter element: specifications & equivalents

The 01.E 90.25VG.HR.E.V.- is a Eaton / Internormen pressure-line hydraulic filter element, built with glass fiber fleece (vg) media, sized 45 × 175 mm OD × length, rated at 20 µm absolute. Verify against the current manufacturer data sheet before ordering.

Envelope OD × L 45 × 175 mm
Filtration rating 20 µm abs.
Media Glass fiber fleece (VG)
Collapse / burst 160 bar
Line type pressure
Catalog verified. Parameters extracted from the manufacturer’s electronic catalog / official interchange document and checked 2026-09-28. Confidence score 0.90.

Specs come from Eaton's product data hub via its site-search API. The µm retention rating follows ISO 16889 (absolute convention), while the model-code fineness grade is nominal — match both before substituting.

How the 01.E 90.25VG.HR.E.V.- model number is decoded

  • 303751Eaton catalog number (order code) for the same element.

Typical equipment & applications

  • Pressure-line hydraulic filters upstream of control valves
  • High-differential-pressure industrial hydraulic circuits
  • Hydraulic power units for steel, paper and power generation

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.
  • Nitrile (NBR) seals are standard for mineral hydraulic oil but fail early in some phosphate-ester fluids and at sustained high temperature; verify seal compound against the fluid data sheet (fluorocarbon/Viton executions may be required).
  • 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 01.E 90.25VG.HR.E.V.- filter element?
The published envelope is 45 mm OD × 175 mm length (1.772 × 6.890 in). Confirm against the housing drawing before ordering.
What micron rating does 01.E 90.25VG.HR.E.V.- use?
This element is rated 20 µm absolute. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the 01.E 90.25VG.HR.E.V.- filter element?
1 partial match(es) requiring parameter review
How do I read the 01.E 90.25VG.HR.E.V.- part number?
See the designation decoder above: each segment of 01E9025VGHREV encodes size, line type, filtration grade and media/collapse execution.
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.
How often should a hydraulic return-line element be replaced?
Replace at the housing manufacturer’s recommended differential-pressure setting (commonly signalled by a clogging indicator), or on a time-based service interval when no indicator is fitted — never wait for bypass to open continuously, because unfiltered oil then reaches the valves.
