Application & Compatibility
The HY-PRO HP518L18-12LORB 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 290 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.
