It is engineered to work with Sierra Riser 18-1938, forming a reliable seal at the riser-to-elbow connection where exhaust heat and cooling water both pass through the joint. As an open gasket, it is cut to allow full flow through the elbow passage rather than restricting it, matching the design of the universal elbow it is paired with.\u003c\/p\u003e\u003cp\u003eThis gasket is also used as part of the Sierra Mounting Kit 18-8547, which is built for use with Riser 18-1938 and includes the 18-0475-1 gasket as a component. Keeping a properly fitted gasket at this joint helps maintain a tight seal in the exhaust cooling system and supports consistent performance of the riser and elbow assembly during service or replacement.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-0475-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Elbow Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Open (universal elbow)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With:\u003c\/strong\u003e Riser 18-1938\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso Included In:\u003c\/strong\u003e Mounting Kit 18-8547\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 98127\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282365806\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Crusader exhaust manifold cooling system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUsed with Crusader inboard exhaust manifold cooling systems, specifically with Riser 18-1938 and Mounting Kit 18-8547.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e98127\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0475-1 gasket used for?\u003c\/strong\u003e The Sierra 18-0475-1 is an open-style exhaust elbow gasket used in Crusader inboard exhaust manifold cooling systems, sealing the joint where the exhaust elbow meets the riser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM number does the 18-0475-1 gasket replace?\u003c\/strong\u003e The 18-0475-1 gasket cross-references to OEM number 98127.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0475-1 gasket weigh?\u003c\/strong\u003e The Sierra 18-0475-1 exhaust elbow gasket weighs 0.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat riser does the 18-0475-1 gasket fit?\u003c\/strong\u003e This gasket, part number 18-0475-1, is designed for use with Sierra Riser 18-1938.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0475-1 gasket included in any kits?\u003c\/strong\u003e Yes, the 18-0475-1 gasket is included as a component in Sierra Mounting Kit 18-8547, which is used with Riser 18-1938.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does open style mean for this elbow gasket?\u003c\/strong\u003e An open gasket, like the 18-0475-1, is cut to allow full flow through the exhaust elbow passage rather than restricting it, matching the universal elbow design it pairs with.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0475-1 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-0475-1 exhaust elbow gasket is 808282365806.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0475-1 gasket come with mounting bolts?\u003c\/strong\u003e The gasket itself, part number 18-0475-1, does not include mounting bolts; those are supplied separately in the Mounting Kit 18-8547.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat system is the 18-0475-1 gasket part of?\u003c\/strong\u003e 18-0475-1 is used in the Crusader exhaust manifold cooling system, specifically at the elbow-to-riser connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-0475-1 gasket be used with any elbow?\u003c\/strong\u003e The 18-0475-1 is an open gasket designed for a universal exhaust elbow and is intended for use with Riser 18-1938.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988075032795,"sku":"SIE-18-0475-1","price":11.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0475_lg__15649.1558120771.500.750.jpg?v=1785188921","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0475-1-exhaust-elbow-gasket-open-oem-98127-for-crusader-inboard-manifold-riser-systems","provider":"Good Vibes Marina","version":"1.0","type":"link"}
