01.E 1201.25G.10.S.V.- filter element: specifications & equivalents

The 01.E 1201.25G.10.S.V.- is a Eaton / Internormen inline-line hydraulic filter element, built with stainless steel wire mesh (g) media, sized 142 × 503 mm OD × length, rated at 25 µm absolute. Verify against the current manufacturer data sheet before ordering.

Envelope OD × L 142 × 503 mm
Filtration rating 25 µm abs.
Media Stainless steel wire mesh (G)
Collapse / burst 10 bar
Line type inline
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 1201.25G.10.S.V.- model number is decoded

  • 01.E 1201.25G.10.S.V.-Eaton 01.E Lubrication filter element model code (Eaton 01.E Lubrication Filter Element).
  • 330763Eaton catalog number (order code) for the same element.
  • 25 GFilter fineness grade: nominal rating and media letter.
  • 25 µmISO 16889 multipass retention rating as published by Eaton.
  • Stainless steel wire mesh (G)Filter media execution.
  • 10 barDelta-P resistance class — maximum differential pressure (collapse) rating.
  • Fluorocarbon (Viton)Seal compound.
  • 142 mmOuter diameter.
  • 503 mmElement height.

Typical equipment & applications

  • Medium-pressure in-line and lubrication circuits
  • Spin-on and exchange element replacements

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 1201.25G.10.S.V.- filter element?
The published envelope is 142 mm OD × 503 mm length (5.591 × 19.803 in). Confirm against the housing drawing before ordering.
What micron rating does 01.E 1201.25G.10.S.V.- use?
This element is rated 25 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 1201.25G.10.S.V.- filter element?
Cross references are being verified for this model — use the inquiry form and the engineering desk will confirm equivalents.
How do I read the 01.E 1201.25G.10.S.V.- part number?
See the designation decoder above: each segment of 01E120125G10SV 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.
