When a hydraulic steering cylinder begins weeping fluid — typically visible as an oily film on the cylinder body or a gradual softening of steering feel — the internal seals are the first place to look. This kit replaces those seals and restores the cylinder to full hydraulic integrity without requiring a complete cylinder replacement.\u003c\/p\u003e\u003cp\u003eAt a fraction of the cost of a new cylinder, a seal kit is the correct first repair step when the cylinder body and ram are in good condition and only the seals have failed.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Dometic replacement seal kit — correct materials and dimensions for hydraulic fluid compatibility\u003c\/li\u003e\n\u003cli\u003eRestores cylinder sealing without full cylinder replacement\u003c\/li\u003e\n\u003cli\u003ePart Number: HS5157 | SKU: 1-HS5157\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eImportant\u003c\/h3\u003e\u003cp\u003eConfirm your cylinder model number before ordering. Dometic produces multiple seal kits for different cylinder families — using the wrong kit will result in an improper fit. The cylinder model number is typically stamped on the cylinder body near the port fittings.

The most common scenario is a customer with a SeaStar or BayStar cylinder reporting fluid weeping or gradual loss of steering resistance. If the cylinder ram is scored or the body is cracked, a seal kit won’t resolve the issue and a full cylinder replacement is the correct path. Recommend professional installation for customers who are not experienced with hydraulic steering systems.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199426265124,"sku":"1-HS5157","price":419.59,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/1-HS5157.jpg?v=1785605244","url":"https:\/\/marisolmarine.com\/products\/dometic-hs5157-hydraulic-cylinder-seal-kit","provider":"Marisol Marine Company","version":"1.0","type":"link"}
