About the Hy-Pro HP33DNL7-40MSB
Hy-Pro HP33DNL7-40MSB is a filter element rated at 40 µm (40 µm nominal), 450 psid collapse pressure, and measuring 3.636 in OD, 1.894 in ID, and 6.45 in length. It uses Microglass media and Nitrile (Buna-N) seals, rated for -45 °F to 225 °F (Hy-Pro 11A-084 drawing).
Application & Compatibility
The HY-PRO HP33DNL7-40MSB 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 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.
