Application & Compatibility
The HY-PRO HP21L4-15ME-WS is designed for use in hydraulic and lubrication filtration systems. With a 15µm nominal (β-rated, absolute 12µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. 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.
