Using a \u003cstrong\u003e1\"-16 UN mounting thread\u003c\/strong\u003e, it removes abrasive contaminants from circulating engine oil while maintaining the flow required to protect bearings, journals, and other lubricated components. The B179 belongs to a widely cross-referenced filter family used across multiple diesel-engine platforms including Cummins, Detroit Diesel, International\/Navistar, Case, and John Deere applications. Always confirm the existing OEM filter number and full engine application before ordering — filters with the same thread can differ in gasket diameter, bypass-valve setting, and internal media.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCummins diesel engines (confirm by existing filter number or engine model)\u003c\/li\u003e\n  \u003cli\u003eDetroit Diesel engine applications\u003c\/li\u003e\n  \u003cli\u003eInternational \/ Navistar diesel engines\u003c\/li\u003e\n  \u003cli\u003eCase diesel equipment\u003c\/li\u003e\n  \u003cli\u003eJohn Deere diesel equipment\u003c\/li\u003e\n  \u003cli\u003eMarine and industrial diesel installations cross-referencing LF3349, WIX 51792, or P550425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfirm engine make, model, serial number, and existing OEM filter number before ordering\u003c\/strong\u003e — the 1\"-16 UN thread is shared across multiple filter sizes with different dimensions and bypass specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDimensions\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThread: 1\"-16 UN\u003c\/li\u003e\n  \u003cli\u003eOutside diameter: approx. 3.69 in. \/ 93.7 mm\u003c\/li\u003e\n  \u003cli\u003eLength: approx. 5.38 in. \/ 136.7 mm\u003c\/li\u003e\n  \u003cli\u003eGasket OD: approx. 2.81 in. \/ 71.4 mm\u003c\/li\u003e\n  \u003cli\u003eGasket ID: approx. 2.42 in. \/ 61.5 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCross-Reference \/ Alternate Part Numbers\u003c\/h3\u003e\n\u003cp\u003eThe following numbers are associated with the Baldwin B179 filter family:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBaldwin:\u003c\/strong\u003e B179\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFleetguard:\u003c\/strong\u003e LF3349\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDonaldson:\u003c\/strong\u003e P550425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWIX:\u003c\/strong\u003e 51792\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNAPA Gold:\u003c\/strong\u003e 1792\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLuber-Finer:\u003c\/strong\u003e LFP4005\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCross-reference numbers are provided as a fitment aid only.

Thread size alone is not sufficient — confirm the body length, gasket diameter, and bypass-valve specification match your application.\u003c\/dd\u003e\n\n  \u003cdt\u003eWhat is the bypass valve setting on the B179?\u003c\/dt\u003e\n  \u003cdd\u003eConfirm the bypass valve specification from the Baldwin catalog or your engine service documentation. Bypass settings vary across heavy-duty filter families even when thread and body dimensions appear identical, and an incorrect bypass setting can affect oil pressure management during cold starts or at high flow rates.\u003c\/dd\u003e\n\n  \u003cdt\u003eCan I substitute Fleetguard LF3349 or WIX 51792 for B179?\u003c\/dt\u003e\n  \u003cdd\u003eThese are in the same cross-reference family, but always confirm the full dimensions, gasket specifications, and bypass setting against your original OEM filter number before substituting brands. Cross-reference lists are a starting point, not a definitive fitment guarantee.\u003c\/dd\u003e\n\n  \u003cdt\u003eWhat happens if I use a filter with the same thread but wrong dimensions?\u003c\/dt\u003e\n  \u003cdd\u003eA filter that threads on correctly but has the wrong body length, gasket diameter, or bypass setting can leak at the gasket, contact surrounding components, or fail to regulate oil pressure correctly. Always compare the new filter physically against the removed filter before installation.\u003c\/dd\u003e\n\n  \u003cdt\u003eShould I change the filter every oil change?\u003c\/dt\u003e\n  \u003cdd\u003eYes — on heavy-duty diesel engines the oil filter should be replaced at every oil change. On high-hours commercial or marine applications, oil analysis can help determine whether more frequent filter changes are warranted based on contamination levels or filter loading rates.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\n\u003chr\u003e\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e The Baldwin B179 is the right choice for customers servicing heavy-duty diesel engines on Cummins, Detroit Diesel, International\/Navistar, Case, or John Deere platforms where the existing filter cross-references to LF3349, WIX 51792, or P550425. At $25.00 it is a cost-effective, high-quality option from one of the most trusted names in heavy-duty filtration. Most B179 orders come from customers doing scheduled maintenance on commercial vessels, generators, or heavy equipment with well-documented service histories — they know their filter number and just need a reliable stocking source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon customer questions:\u003c\/strong\u003e The most frequent issue is customers assuming thread size is sufficient to confirm fitment on a heavy-duty filter. The 1\"-16 UN thread appears on several Baldwin filter families with different body lengths and gasket dimensions. Always ask for the OEM filter number or the existing filter part number before confirming the order. The second common point of confusion is substituting cross-reference numbers without checking bypass valve specifications — particularly important on Cummins and Detroit Diesel applications where oil pressure management is tightly specified.\u003c\/p\u003e","brand":"FVW","offers":[{"title":"Default Title","offer_id":43563795218468,"sku":"B179","price":25.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_bd44e4e5-5f81-49e2-85a5-076acfb004ed.jpg?v=1788803294","url":"https:\/\/marisolmarine.com\/products\/baldwin-b179-heavy-duty-spin-on-oil-filter","provider":"Marisol Marine Company","version":"1.0","type":"link"}
