Each gasket is made from a stainless steel infused graphite material engineered for superior compressibility, helping the gasket seal effectively against the pressures and heat cycling found in a marine exhaust elbow joint. A tight, consistent seal at this connection point helps prevent exhaust leaks and the corrosion that can follow when combustion gases or water escape past a worn or hardened gasket.\u003c\/p\u003e\u003cp\u003eThis gasket is the component specified for elbow 18-1973 and is also included as part of mounting kit 18-8508. It corresponds to OEM reference number 27-39915, so it can be used as a direct replacement when that number is called for. Sierra backs this gasket with its standard product warranty, and each package contains two gaskets so a spare is on hand for the next service interval.\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 18-2819-1-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2 (Pack of 2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel Infused Graphite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 1 centimeter L x 17.5 centimeters W x 17.7 centimeters H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282369170\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Elbow:\u003c\/strong\u003e 18-1973\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded In Mounting Kit:\u003c\/strong\u003e 18-8508\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 27-39915\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Taiwan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with exhaust elbow 18-1973 and included in mounting kit 18-8508.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e27-39915\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat elbow does the Sierra 18-2819-1-9 gasket fit?\u003c\/strong\u003e The 18-2819-1-9 gasket is designed for use with exhaust elbow 18-1973 and is also included in mounting kit 18-8508.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-2819-1-9 the same as OEM part 27-39915?\u003c\/strong\u003e Yes, Sierra's 18-2819-1-9 elbow gasket corresponds to OEM cross-reference number 27-39915, so it can be installed as a replacement for that part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package of 18-2819-1-9?\u003c\/strong\u003e Each package contains 2 gaskets, so you get a spare for future service in addition to the one needed for the current job.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the exhaust elbow gasket made from?\u003c\/strong\u003e It is made of a stainless steel infused graphite material, chosen for its compressibility and ability to seal well under exhaust heat and pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the 18-2819-1-9 gasket?\u003c\/strong\u003e The gasket is round in shape, matching the mounting profile of exhaust elbow 18-1973.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2819-1-9 gasket weigh?\u003c\/strong\u003e A package of the 18-2819-1-9 exhaust elbow gasket weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this gasket be used with the 18-8508 mounting kit?\u003c\/strong\u003e Yes, the 18-2819-1-9 gasket is the same elbow gasket included in Sierra's 18-8508 mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2819-1-9 gasket genuine Sierra or aftermarket?\u003c\/strong\u003e It is a genuine Sierra part, backed by Sierra's product warranty, rather than a generic aftermarket substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order 18-2819-1-9?\u003c\/strong\u003e You receive a pack of 2 exhaust elbow gaskets, part number 18-2819-1-9, with no additional hardware included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the Sierra 18-2819-1-9 gasket manufactured?\u003c\/strong\u003e This gasket's country of origin is Taiwan.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988129853659,"sku":"SIE-18-2819-1-9","price":10.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2819-1-9__90938.1558335092.500.750.jpg?v=1785187993","url":"https:\/\/www.goodvibesmarina.com\/products\/exhaust-elbow-gasket-replaces-27-39915-fits-sierra-18-1973-exhaust-elbow-2-pack","provider":"Good Vibes Marina","version":"1.0","type":"link"}
