Application & Compatibility
The HYDAC 1272566 is designed for use in hydraulic and lubrication filtration systems. With a 10µm rating, this element is suitable for proportional valve protection and general hydraulic systems. Buna-N/Nitrile seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 250 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.
