Application & Compatibility

The DONALDSON P171803 is designed for use in hydraulic and lubrication filtration systems. With a 27µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits. BUNA seals provide compatibility with standard petroleum-based fluids and mineral oils.

The 145 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.
