Application & Compatibility
The HY-PRO HP78RNL12-3MB-50 is designed for use in hydraulic and lubrication filtration systems. With a 3µm nominal (β-rated, absolute 4µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Buna-N seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 250 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.
