Application & Compatibility
The PARKER 933812Q is designed for use in hydraulic and lubrication filtration systems. With a 20µm rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Buna-N seals provide compatibility with standard petroleum-based fluids and mineral oils.
The 50 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.
