The SeaStar HA5450 Remote Fill & Vent Plug Kit is designed for SS1250V and SS1275V hydraulic steering helms, giving boaters a simple way to fill and vent the hydraulic steering system during initial setup or routine maintenance. Proper filling and venting of a hydraulic helm is essential to removing trapped air from the system, which helps maintain smooth, consistent steering response at the wheel. The kit features a polished exterior finish that matches typical helm and dash hardware, so it installs cleanly without looking out of place. Because it is purpose-built for the SS1250V and SS1275V helm models, it is sized and configured to thread directly into the fill and vent ports on those units without modification. This kit is a practical item to have on hand for boat builders, dealers, and boat owners performing steering system fills, bleeds, or fluid top-offs, and it is a straightforward way to replace a lost, damaged, or corroded original fill/vent plug on a compatible helm.
