04.PI 3215.10VG.HR.E.O filter element: specifications & equivalents

Q: What are the dimensions of the 04.PI 3215.10VG.HR.E.O filter element?

The published envelope is 83 mm OD × 144.5 mm length (3.268 × 5.689 in). Confirm against the housing drawing before ordering.

Q: What micron rating does 04.PI 3215.10VG.HR.E.O use?

This element is rated 10 µm absolute. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The 04.PI 3215.10VG.HR.E.O is a Eaton / Internormen inline-line hydraulic filter element, built with glass fiber fleece (vg) media, sized 83 × 144.5 mm OD × length, rated at 10 µm absolute. Verify against the current manufacturer data sheet before ordering.

Envelope OD × L 83 × 144.5 mm

Filtration rating 10 µm abs.

Media Glass fiber fleece (VG)

Collapse / burst 160 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.

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 04.PI 3215.10VG.HR.E.O filter element?

The published envelope is 83 mm OD × 144.5 mm length (3.268 × 5.689 in). Confirm against the housing drawing before ordering.

What micron rating does 04.PI 3215.10VG.HR.E.O use?

This element is rated 10 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 04.PI 3215.10VG.HR.E.O filter element?

5 partial match(es) requiring parameter review

How do I read the 04.PI 3215.10VG.HR.E.O part number?

See the designation decoder above: each segment of 04PI321510VGHREO 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.
