Application & Compatibility

The HY-PRO HP306NL3-25ME-WS is designed for use in hydraulic and lubrication filtration systems. With a 25µm nominal (β-rated, absolute 22µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. EPR (Ethylene Propylene) seals provide compatibility with standard petroleum-based fluids and mineral oils.

The 450 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.
