Meyer M2 Hydraulic Flush Keeping your hydraulic unit internally clean is as important as keeping your engine clean. Meyer’s M2 Hydraulic Flush is designed to scrub the internal components and flush away all impurities that may have developed in the system. Our exclusively designed M2 Flush is designed to perform without harming seals, connectors or hydraulic ports. It is recommended that you drain the M1 Hydraulic in the spring, fill and store the unit with Hydra-Flush over the summer & re-fill with new M1 Hydraulic fluid in the fall.
