Application & Compatibility
The HY-PRO HP25L9-40MB is designed for use in hydraulic and lubrication filtration systems. With a 40µm nominal (β-rated, absolute 52µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Nitrile (Buna) 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.
