The bottom line is that this kit is for technicians, maintenance crews, and hobbyists who need a durable, high-temperature sealing solution that resists fuels, oils and many solvents. The reviewer found the o-rings to match nominal AS568 sizing, offer a firm 90A durometer for compressive sealing, and perform reliably across a wide temperature range, making them a practical choice for demanding sealing tasks.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Viton (fluorocarbon rubber) provides excellent resistance to fuels, mineral oils and many organic solvents for longer seal life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurometer:\u003c\/strong\u003e The 90A hardness gives a firm cross-section that holds compression well under mechanical loads and repeated cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature range:\u003c\/strong\u003e Rated from -26C to 232C (-15F to 450F), it suits high-temperature air, engine and industrial applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExact sizing:\u003c\/strong\u003e Actual dimensions are provided so installers can match 13.984in ID and 14.262in OD to existing grooves for a reliable fit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack quantity:\u003c\/strong\u003e Pack of 5 supplies spare parts for routine maintenance or replacement on multiple systems without buying single pieces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical compatibility:\u003c\/strong\u003e Performs well with petroleum, diesel, biodiesel blends, methanol or ethanol blends, and many greases and oils.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Mr O-Ring 280 Viton o-ring is aimed at professionals and experienced DIYers who need a robust, high-temperature seal that complies with common AS568 sizing.
