About the Hy-Pro HP28NL7-3AV
Hy-Pro HP28NL7-3AV is a filter element rated at 4 µm (3 µm nominal), a beta ratio of β ≥ 4000, 450 psid collapse pressure, and measuring 2.36 in OD, 1.39 in ID, and 6.91 in length. It uses Dualglass + Water Removal media and Fluorocarbon (Viton) seals, rated for -20 °F to 250 °F (Hy-Pro datasheet).
Application & Compatibility
The HY-PRO HP28NL7-3AV 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. Fluorocarbon (Viton) seals provide compatibility with petroleum-based fluids, synthetic fluids, phosphate esters, and water-glycol mixtures.
The 450 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.
