HF6237 filter element: specifications & equivalents

Q: What micron rating does HF6237 use?

This element is rated 45 µm absolute — 45 µm at β75(c) per ISO 16889. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The HF6237 is a Fleetguard inline-line hydraulic filter element, rated at 45 µm absolute (45 µm at β75(c) per ISO 16889). Verify against the current manufacturer data sheet before ordering.

Inside diameter 152.65 mm

Filtration rating 45 µm abs.

Beta rating 45 µm at β75(c) per ISO 16889

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.

Specifications and cross-references are taken from the Fleetguard online catalog API. Where both TWA and Beta ratings are published the conventions differ — verify cleanliness targets, collapse rating and seal configuration against the current Fleetguard 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.
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 micron rating does HF6237 use?

This element is rated 45 µm absolute — 45 µm at β75(c) per ISO 16889. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

What replaces the HF6237 filter element?

74 partial match(es) requiring parameter review

How do I read the HF6237 part number?

See the designation decoder above: each segment of HF6237 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.
