404211 filter element: specifications & equivalents
The 404211 is a Eaton / Internormen inline-line hydraulic filter element. Verify against the current manufacturer data sheet before ordering.
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.

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.
