Kleenoil bypass filtration works alongside your engine’s full-flow filter to continuously clean a portion of the oil to a much finer level — removing sub-micron particles, water, fuel dilution, and combustion acids that a standard full-flow filter cannot capture. This cartridge is the consumable element at the heart of that system and must be replaced at regular service intervals to maintain filtration performance.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eBest suited for \u003cstrong\u003ediesel inboard engines running a Kleenoil KU50 or 9778 bypass filtration unit\u003c\/strong\u003e — a common fitment on commercial vessels, workboats, and serious cruising sailboats where extended oil life and engine protection are priorities. Bypass filtration is particularly valuable in high-hour engines, engines operating in dusty or contaminated environments, or anywhere extended oil change intervals are desired. Replace this cartridge according to your Kleenoil service schedule — typically every 250–500 engine hours or annually, whichever comes first. Do not attempt to clean or reuse the cartridge. Confirm your unit model number (KU50 or 9778) matches before ordering, as cartridge compatibility is model-specific.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGenuine replacement cartridge for Kleenoil KU50 and 9778 bypass filter units\u003c\/li\u003e\n\u003cli\u003eRemoves sub-micron particles, water, fuel dilution, and combustion acids\u003c\/li\u003e\n\u003cli\u003eExtends engine oil life and reduces wear on critical engine components\u003c\/li\u003e\n\u003cli\u003eDirect drop-in replacement — no modifications required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e KF50-1878\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Units:\u003c\/strong\u003e Kleenoil KU50, 9778\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type:\u003c\/strong\u003e Bypass oil filtration cartridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Marine diesel inboard engines\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LES","offers":[{"title":"Default Title","offer_id":43765915549732,"sku":"KF50-1878","price":235.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/b66a8d1d-2a33-4bce-b321-14704dcbb36c.png?v=1785965931","url":"https:\/\/marisolmarine.com\/products\/kleenoil-ku50-bypass-oil-filter-replacement-cartridge-kf50-1878","provider":"Marisol Marine Company","version":"1.0","type":"link"}
