About the Hy-Pro HP4NL4-20MB-N
Hy-Pro HP4NL4-20MB-N is a filter element rated at 20 µm (20 µm nominal), a beta ratio of β ≥ 1000, 290 psid collapse pressure, and measuring 2.49 in OD, 1.29 in ID, and 4 in length. It uses microglass media and Nitrile (Buna-N) seals (Hy-Pro 12G-010 drawing).
Application & Compatibility
The HY-PRO HP4NL4-20MB-N is designed for use in hydraulic and lubrication filtration systems. With a 20µm 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 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.
