HF6850 filter element: specifications & equivalents
The HF6850 is a Fleetguard inline-line hydraulic filter element, sized 76.5 × 195 mm OD × length (ID 48.5 mm), rated at 10 µm absolute (10 µm at β75(c) per ISO 16889). Verify against the current manufacturer data sheet before ordering.
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.

How the HF6850 model number is decoded
- HF6850Fleetguard HF-series hydraulic cartridge element part number.
- 195 mmOverall height.
- 76.5 mmLargest outside diameter.
- 48.5 mmLargest end inside diameter.
- 10 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.
