SeaStar Hydraulic Steering Oil, 32 fl oz (1 Liter), Part HA5430H
SeaStar Hydraulic Oil is the fluid specified for use in SeaStar hydraulic steering systems. Supplied in a 32 fluid ounce (1 liter) bottle, it is formulated to maintain proper lubrication and consistent hydraulic response through the helm pump, cylinder, and steering lines. Using the correct hydraulic fluid is essential to keeping a hydraulic steering system operating smoothly, since the wrong fluid type can degrade seals or cause inconsistent steering feel over time.
This oil is intended for topping off fluid levels or performing a full system fill or bleed during routine maintenance, after installing a new SeaStar steering system, or when servicing helm pumps and cylinders. Keeping fresh hydraulic fluid in the system helps prevent air entrapment and supports consistent, predictable steering response at the helm.
