How the HF6330 model number is decoded

  • HF6330Fleetguard HF-series hydraulic cartridge element part number.
  • 240 mmOverall height.
  • 149 mmLargest outside diameter.
  • 83 mmLargest end inside diameter.
  • 57 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 are the dimensions of the HF6330 filter element?
The published envelope is 149 mm OD × 240 mm length with a 83 mm inside diameter (5.866 × 9.449 in × 3.268 in ID). Confirm against the housing drawing before ordering.
What micron rating does HF6330 use?
This element is rated 57 µm absolute — 57 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 HF6330 filter element?
29 partial match(es) requiring parameter review
How do I read the HF6330 part number?
See the designation decoder above: each segment of HF6330 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.
