How the HF7797 model number is decoded

  • HF7797Fleetguard HF-series hydraulic cartridge element part number.
  • 230.12 mmOverall height.
  • 112.52 mmLargest end inside diameter.
  • 25 µm at β75(c) per ISO 16889Published efficiency ratings.

Typical equipment & applications

  • Construction, agricultural and industrial hydraulic circuits
  • Mobile-equipment hydraulic return and pressure lines

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 HF7797 use?
This element is rated 25 µm absolute — 25 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 HF7797 filter element?
14 partial match(es) requiring parameter review
How do I read the HF7797 part number?
See the designation decoder above: each segment of HF7797 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.
