The bottom line: these 90A durometer Viton rings stand out for their high temperature and chemical resistance, making them a practical choice when working with petroleum fuels, hydraulic fluids or hot-air applications. The pack of 50 reduces downtime from sourcing individual rings and supplies a standard AS568-compatible size for repeatable replacements.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e FKM Viton composition offers strong resistance to high temperature, ozone and many organic solvents so seals last longer under harsh conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurometer:\u003c\/strong\u003e 90A hardness provides a firm sealing surface that resists extrusion in moderate to high pressure applications while maintaining elasticity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal and actual sizes:\u003c\/strong\u003e the nominal 1-5\/8 in ID and 1-13\/16 in OD correspond to actual measured 1.612 in ID and 1.818 in OD for predictable fit in AS568-sized grooves.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature range:\u003c\/strong\u003e usable from -26C (-15F) to 232C (450F), covering most hot-air, engine and industrial fluid environments where standard elastomers fail.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical compatibility:\u003c\/strong\u003e performs well with petroleum products, diesel and biodiesel blends, mineral oils, silicone oils and many strong acids, reducing seal failure across applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValue pack:\u003c\/strong\u003e sold in quantities of 50, this pack lowers per-piece cost and keeps common replacement stock on hand for maintenance teams.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis pack suits maintenance shops, industrial fabricators and anyone servicing fuel, hydraulic or high-temperature equipment who needs a standard AS568-size Viton O-ring in bulk.
