A cross-reference confirms dimensional fit and micron rating, not performance equivalence. Beta ratio, collapse rating, media, and service life can differ between brands.
Cross-references on file
Each row carries its own evidence status. Verified: confirmed against a source document. Sourced: taken from a published cross list, not independently confirmed. Transitive: derived through a chain of published crosses. None is an application-compatibility approval.

Application & Compatibility
The WESTERN E3041BU03 is designed for use in hydraulic and lubrication filtration systems. With a 4µm rating, this element is suitable for servo valve protection and high-precision hydraulic systems. Nitrile (Buna-N) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 290 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.
