Stop steering leaks and slop the right way. The Oni Tools Hydraulic Steering Cylinder Reseal Kit pairs an HS5157-style seal set, a support bracket puller and pin wrench so marine techs and DIYers can reseal front-mount cylinders quickly and correctly. The kit targets popular SeaStar front-mount cylinder models including HC5341–HC5375, HC5394, HC5445, HC6750–HC6755 (verify your cylinder ID; HC5340 excluded). The heavy-duty black-oxide steel puller breaks seized support brackets free without damage, while aluminum gland tools and included O-rings help restore leak-tight performance and crisp helm feel. Use it on single or twin outboard applications to eliminate weeping seals, prevent fluid loss, and extend cylinder life—on the water, reliability matters. (Bracket puller also fits SeaStar & Uflex support brackets.)
