HF6782 filter element: specifications & equivalents

Q: What are the dimensions of the HF6782 filter element?

The published envelope is 128.93 mm OD × 272.01 mm length (5.076 × 10.709 in). Confirm against the housing drawing before ordering.

Q: What micron rating does HF6782 use?

This element is rated 21 µm absolute — 21 µm at β75(c); 23 µm at β200(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 HF6782 is a Fleetguard return-line hydraulic filter element, sized 128.93 × 272.01 mm OD × length, rated at 21 µm absolute (21 µm at β75(c); 23 µm at β200(c) per ISO 16889). Verify against the current manufacturer data sheet before ordering.

Selection pitfalls — read before you substitute

A return-line element is not a pressure-line element: return cartridges (BN4HC low-collapse) tolerate roughly 20 bar differential, while BH4HC pressure executions are rated to 210 bar. Installing a low-collapse element in a pressure housing can rupture the media on cold-start spikes.
This element has no integral bypass — opening pressure is set by the housing’s reusable bypass valve. Confirm the valve setting (commonly 3.4 bar) is present before fitting.
“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 HF6782 filter element?

The published envelope is 128.93 mm OD × 272.01 mm length (5.076 × 10.709 in). Confirm against the housing drawing before ordering.

What micron rating does HF6782 use?

This element is rated 21 µm absolute — 21 µm at β75(c); 23 µm at β200(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 HF6782 filter element?

99 partial match(es) requiring parameter review

How do I read the HF6782 part number?

See the designation decoder above: each segment of HF6782 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.
