It seals the connection between the manifold elbow riser and the exhaust system, and is built to the exact fit required for the 18-1939 and 18-1999 manifold elbow risers. This gasket is also included as a component of the Sierra 18-8535 mounting kit, which is the blocked-gasket mounting package used with these risers.\u003c\/p\u003e\u003cp\u003eBecause it is the blocked-style gasket, the 18-0476-1 is intended for closed cooling system exhaust setups rather than open-style configurations. Buyers replacing a worn or leaking riser gasket, or assembling a complete blocked mounting kit, can use this part on its own or alongside the 18-8535 kit components. A direct OEM cross-reference to Barr Marine part 01-0105 is available for buyers matching this gasket against an existing part number.\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 18-0476-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Elbow Gasket (Blocked)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling System Application:\u003c\/strong\u003e Closed cooling system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Risers:\u003c\/strong\u003e 18-1939, 18-1999\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded In Mounting Kit:\u003c\/strong\u003e 18-8535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Barr Marine 01-0105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282363635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUsed with 3 1\/2 inch manifold elbow riser 18-1939\u003c\/li\u003e\n\u003cli\u003eUsed with 3 1\/2 inch manifold elbow riser 18-1999\u003c\/li\u003e\n\u003cli\u003eIncluded in the 18-8535 blocked mounting kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eBarr Marine 01-0105\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0476-1 gasket used for?\u003c\/strong\u003e It is a blocked-style elbow gasket that seals the connection between a manifold elbow riser and the exhaust system on a closed cooling system setup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich risers does the 18-0476-1 gasket fit?\u003c\/strong\u003e The 18-0476-1 is used with the 18-1939 and 18-1999 manifold elbow risers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0476-1 a blocked or open style gasket?\u003c\/strong\u003e It is the blocked-style elbow gasket, intended for closed cooling system exhaust riser installations rather than open-style setups.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0476-1 gasket come as part of a mounting kit?\u003c\/strong\u003e Yes, the 18-0476-1 elbow gasket is included in the Sierra 18-8535 blocked mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there an OEM equivalent number for the 18-0476-1 gasket?\u003c\/strong\u003e Barr Marine 01-0105 is the OEM cross-reference number for the Sierra 18-0476-1 elbow gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 18-0476-1 and 18-2854-1 gaskets?\u003c\/strong\u003e The 18-0476-1 is the blocked-style gasket for closed cooling systems, while the 18-2854-1 is the corresponding 3 inch open-style gasket included in the 18-4364 mounting kit; both are used with the same 18-1939 and 18-1999 risers but are not interchangeable with each other.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0476-1 elbow gasket weigh?\u003c\/strong\u003e The Sierra 18-0476-1 elbow gasket weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-0476-1 gasket be used with the 18-4364 mounting kit?\u003c\/strong\u003e No, the 18-0476-1 is the blocked-style gasket used with the 18-8535 mounting kit; the 18-4364 kit uses the open-style 18-2854-1 gasket instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0476-1 gasket suitable for Volvo Penta exhaust manifold systems?\u003c\/strong\u003e Yes, the Sierra 18-0476-1 blocked elbow gasket is used in Volvo Penta exhaust manifold riser applications with the 18-1939 and 18-1999 risers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat cooling system setup requires the 18-0476-1 blocked gasket?\u003c\/strong\u003e A closed cooling system requires the blocked-style gasket design used by the Sierra 18-0476-1.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988075131099,"sku":"SIE-18-0476-1","price":8.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0476_lg__21620.1659362476.500.750.jpg?v=1785329157","url":"https:\/\/www.goodvibesmarina.com\/products\/riser-gasket-18-0476-1-for-blocked-locked-center-riser-exhaust-manifold-crusader-interceptor-mercury-omc","provider":"Good Vibes Marina","version":"1.0","type":"link"}
