About the Hy-Pro HP456L21-40PB-3
Hy-Pro HP456L21-40PB-3 is a filter element rated at 40 µm (40 µm nominal), a beta ratio of β ≥ 1000, 70 psid collapse pressure, and measuring 3.9 in OD, 2.2 in ID, and 21 in length. It uses synthetic media and Nitrile (Buna-N) seals (Hy-Pro datasheet).
Application & Compatibility
The HY-PRO HP456L21-40PB-3 is designed for use in hydraulic and lubrication filtration systems. With a 40µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Nitrile (Buna-N) seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 70 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.
