Application & Compatibility

The HY-PRO HP511L9-12MB 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.
