Application & Compatibility
The HY-PRO HP44L4-1AE is designed for use in hydraulic and lubrication filtration systems. With a 1µm rating, this element is suitable for servo valve protection and high-precision hydraulic systems. Ethylene Propylene (EPR) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 425 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.
