Application & Compatibility
The DONALDSON P173618 is designed for use in hydraulic and lubrication filtration systems. With a 7µm rating, this element is suitable for proportional valve protection and general hydraulic systems. 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.

How this entry is verified
Every specification on this page names its source: manufacturer documents first, distributor catalogs second, decoded part-number patterns labeled as such. When a value has not been verified from an OEM source, the cell says so. Cross-references are fit claims, never performance claims.
