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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e SeaStar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e HA5430H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 32 fluid ounces (1 liter)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.89 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Hydraulic Boat Steering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Hydraulic steering fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is SeaStar Hydraulic Oil used for?\u003c\/strong\u003e SeaStar Hydraulic Oil (part HA5430H) is used to fill, top off, or bleed SeaStar hydraulic steering systems, including the helm pump, cylinder, and connecting lines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much fluid comes in one bottle of HA5430H?\u003c\/strong\u003e Each bottle of SeaStar Hydraulic Oil holds 32 fluid ounces, which is equal to 1 liter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does a bottle of SeaStar Hydraulic Oil weigh?\u003c\/strong\u003e A bottle of HA5430H weighs 1.89 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use this oil for a full system fill on a new SeaStar steering setup?\u003c\/strong\u003e Yes, SeaStar Hydraulic Oil is suitable for a full fill and bleed of a SeaStar hydraulic steering system, not just topping off existing fluid.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs SeaStar Hydraulic Oil only for SeaStar branded steering systems?\u003c\/strong\u003e SeaStar Hydraulic Oil, part HA5430H, is the fluid designated for SeaStar hydraulic steering systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should hydraulic steering fluid be replaced?\u003c\/strong\u003e The dossier for HA5430H does not specify a replacement interval; check your steering system's fluid level periodically and top off with SeaStar Hydraulic Oil as needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if the wrong fluid is used in a hydraulic steering system?\u003c\/strong\u003e Using a fluid other than the one specified, such as SeaStar Hydraulic Oil for SeaStar systems, can affect seal performance and steering consistency, which is why the correct fluid type matters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this bottle include a pump or applicator?\u003c\/strong\u003e The listing for HA5430H is for the 32 fluid ounce bottle of hydraulic oil itself; no additional accessories are specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs HA5430H the genuine SeaStar part number?\u003c\/strong\u003e Yes, HA5430H is the SeaStar part number for this 32 fluid ounce (1 liter) bottle of hydraulic steering oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size container does SeaStar Hydraulic Oil come in?\u003c\/strong\u003e SeaStar Hydraulic Oil, part HA5430H, comes in a 32 fluid ounce (1 liter) bottle.\u003c\/p\u003e","brand":"SeaStar","offers":[{"title":"Default Title","offer_id":48989347610843,"sku":"TEL-HA5430H","price":27.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/HA5430H__14255.1723556987.500.750.jpg?v=1785329141","url":"https:\/\/www.goodvibesmarina.com\/products\/seastar-hydraulic-steering-oil-ha5430h-32-fl-oz-1-liter-marine-steering-fluid","provider":"Good Vibes Marina","version":"1.0","type":"link"}
