About the Hy-Pro HP25SL9-12AB
Hy-Pro HP25SL9-12AB is a filter element rated at 12 µm (12 µm nominal), a beta ratio of β ≥ 4000, 150 psid collapse pressure, and measuring 2.498 in OD, 1.21 in ID, and 9.62 in length. It uses Dualglass + Water Removal media and Nitrile (Buna-N) seals, rated for -45 °F to 225 °F (Donaldson Hy-Pro HP101 Data Sheet FE-101-071724, p.4).
Application & Compatibility
The HY-PRO HP25SL9-12AB is designed for use in hydraulic and lubrication filtration systems. With a 12µm rating, this element is suitable for proportional valve protection and general hydraulic systems. Nitrile (Buna-N) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 150 PSID collapse rating indicates the maximum differential pressure this element can withstand during cold starts or bypass conditions without structural failure. Ensure your system's maximum differential pressure does not exceed this rating.
