Application & Compatibility
The HY-PRO HP66RNL18-25MV is designed for use in hydraulic and lubrication filtration systems. With a 25µm nominal (β-rated, absolute 22µm) rating, this element is suitable for pump and component protection in industrial hydraulic circuits. Fluorocarbon (Viton) seals provide compatibility with petroleum-based fluids, synthetic fluids, phosphate esters, and water-glycol mixtures.
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.
