About the Hy-Pro HP66RNL40-6LCV
Hy-Pro HP66RNL40-6LCV is a filter element rated at 6 µm (6 µm nominal), a beta ratio of β ≥ 4000, 250 psid collapse pressure, and measuring 4.48 in OD, 2.71 in ID, and 40.63 in length. It uses G8 Dualglass (Low Temp) media and Viton seals (Hy-Pro datasheet).
Application & Compatibility
The HY-PRO HP66RNL40-6LCV 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. 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.
