The hydraulic steering bleed kit is designed for cleaning boat hydraulic steering systems. Made of brass material, the kit helps prevent rust and extends service life. Size L: 35 inches (90 cm). To use, connect a bottle of sea star hydraulic steering fluid to the filling hose cap, insert the filling fitting into the hydraulic steering fill port, and attach the quick connector on the other end of the filling hose to the fitting. Insert one end of the bleeding hose into the oil outlet fitting of the hydraulic steering cylinder, and connect the other end to the quick connector. Invert the hydraulic steering fluid bottle so the fluid flows through the filling hose into the system, then exits via the bleeding hose and fitting, achieving a thorough cleaning effect.
