About the Hy-Pro HP21L8-300WB

Hy-Pro HP21L8-300WB is a filter element rated at 300 µm (300 µm nominal), a beta ratio of β ≥ 200, 3000 psid collapse pressure, and measuring 1.735 in OD, 1.025 in ID, and 8.18 in length. It uses Wire Mesh media and Nitrile (Buna) seals, rated for -45 °F to 225 °F (Hy-Pro part number decoder).

Application & Compatibility

The HY-PRO HP21L8-300WB is designed for use in hydraulic and lubrication filtration systems. With a 300µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Nitrile (Buna) seals provide compatibility with standard petroleum-based fluids and mineral oils.

The 3000 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.
