The bottom line: this single-pack Viton o-ring is for professionals and hobbyists who need a robust, high-temperature seal that resists fuels, oils and many solvents. It stands out because the 90A durometer formulation keeps a tight cross-section under stress while tolerating temperatures up to 232C, making it a practical replacement or spare for equipment exposed to harsh fluids or high heat.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e460 Viton material:\u003c\/strong\u003e offers broad chemical resistance, so it performs well with petroleum, fuel blends and many organic solvents without rapid degradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90A durometer:\u003c\/strong\u003e delivers a firm seal that resists extrusion and maintains shape under pressure for reliable sealing in demanding applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal and actual sizes:\u003c\/strong\u003e nominal 15-1\/2in ID with actual measured ID 15.475in and OD 16.025in, providing clarity for exact fit checks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide temperature range:\u003c\/strong\u003e rated from -26C to 232C, enabling use across cold starts and very high temperature operating conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAS568 size standard:\u003c\/strong\u003e built to industry sizing, which simplifies replacement and compatibility with existing grooves and housings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShelf-life unlimited:\u003c\/strong\u003e can be stored as a spare without worrying about expiration, useful for maintenance kits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis o-ring is aimed at technicians, fabricators and maintenance professionals who need a dependable seal in environments involving fuels, hydraulic fluids, silicone oils, or elevated temperatures.
