Application & Compatibility

The HY-PRO HP21L4-6ME is designed for use in hydraulic and lubrication filtration systems. With a 6µm rating, this element is suitable for proportional valve protection and general hydraulic systems. EPR (Ethylene Propylene) 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.
