Application & Compatibility
The DONALDSON P162181 is designed for use in hydraulic and lubrication filtration systems. With a 9µm rating, this element is suitable for proportional valve protection and general hydraulic systems.
The 100 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.
