Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist familiar with high-pressure hose assembly practices. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fitting. Inspect the O-ring sealing surface for damage before assembly, and ensure the O-ring is properly seated to achieve a leak-free Seal-Lok connection. Torque the fitting according to the system designer or hose assembly manufacturer guidelines for the applicable thread size.
