It carries an inside diameter of 0.215 inch and a width of 0.065 inch, dimensions that match the original equipment seal it replaces. This O-ring is used within the drive system O-ring and oil seal group for Chrysler\/Force outboards, where a tight, reliable seal is needed to keep water out and lubricant in around drive-train components.\u003c\/p\u003e\u003cp\u003eAs a replacement part, the Sierra 18-7120 is intended to restore a factory-correct seal when servicing the drive system, helping prevent water intrusion or lubricant leakage that can lead to corrosion or component wear. Its compact size makes it a low-cost, easy-to-stock component for routine maintenance and drive system rebuilds.\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 18-7120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter:\u003c\/strong\u003e 0.215 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 0.065 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Outboard Drive Systems O-Ring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eChrysler\/Force outboard drive systems\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e25-F498618\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7120 O-ring fit?\u003c\/strong\u003e The Sierra 18-7120 O-ring is designed for Chrysler\/Force outboard drive systems, where it seals a drive component to keep water out and lubricant in.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the OEM equivalent for part 18-7120?\u003c\/strong\u003e Part 18-7120 replaces OEM number 25-F498618, so it is a direct substitute for that original equipment seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the 18-7120 O-ring?\u003c\/strong\u003e It measures 0.215 inch inside diameter by 0.065 inch in width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7120 O-ring weigh?\u003c\/strong\u003e The Sierra 18-7120 weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7120 a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-7120 is a Sierra-branded replacement part manufactured to match the original equipment O-ring it replaces, part number 25-F498618.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere in the outboard is this O-ring used?\u003c\/strong\u003e This O-ring is part of the drive system O-ring and oil seal group used in Chrysler\/Force outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-7120?\u003c\/strong\u003e Ordering the Sierra 18-7120 gets you the single replacement O-ring sized 0.215 inch ID by 0.065 inch width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace this O-ring during service?\u003c\/strong\u003e A worn or hardened O-ring in the drive system can allow water intrusion or lubricant leakage, so replacing the 18-7120 during service helps maintain a proper seal in Chrysler\/Force outboard drive systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7120 cross-reference to more than one OEM number?\u003c\/strong\u003e The Sierra 18-7120 cross-references to OEM number 25-F498618.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7120 O-ring specific to certain outboard brands?\u003c\/strong\u003e Yes, the 18-7120 is designated for Chrysler\/Force outboard drive systems.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988364144859,"sku":"SIE-18-7120","price":0.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7120_lg__59868.1558131277.500.750.jpg?v=1785329171","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7120-o-ring-for-chrysler-force-outboard-drive-systems-replaces-25-f498618-and-31-f523143","provider":"Good Vibes Marina","version":"1.0","type":"link"}
