Question by: Phil F on Sep 2, 2025, 1:14 PM

What kind of fluid can I run through this filter? Just regular hydraulic oil, or can it handle somethin' else?

Suitable for mineral oils, this filter can handle other fluids, though you'd need to make a specific request to ensure proper seal compatibility.
