SeaStar Helm Pump Seal Kit, 1 Inch Shaft, HS5201 - Fits HH5279-3, HH5280-3, HH5281-3 Rear Mount Cylinders

The SeaStar HS5201 is a 1 inch shaft seal kit for SeaStar hydraulic steering helm pump cylinders. It is the seal kit specified for the SeaStar 1.4 rear mount cylinder with a 1 inch straight shaft (HH5279-3), the SeaStar 1.4 rear mount cylinder with a 1 inch tapered shaft (HH5280-3), and the SeaStar 1.7 rear mount cylinder with a 1 inch tapered shaft (HH5281-3). Boat owners and marine technicians use this kit to restore proper sealing inside these helm pump cylinder assemblies when a steering system starts to feel spongy, loses pressure, or shows signs of hydraulic fluid seepage around the shaft. Because HS5201 is shared across three different SeaStar rear mount cylinder part numbers, it lets a shop stock a single seal kit to service multiple helm pump builds within the 1.4 and 1.7 rear mount lineup, provided the shaft is the 1 inch size. At 0.06 pounds, the kit ships and stores easily as a small parts-bin item alongside other helm pump service components.
