حلقات O من Viton FKM | قطر داخلي 2.6 بوصة × قطر مقطع 0.21 بوصة | AS568-334 | داش 334 | صلابة 90 (25/عبوة)

I needed a reliable seal for a hydraulic fitting that sees constant heat cycling, and the 90 durometer hardness on these Viton rings gives me confidence they won't soften or fail early. The -15°F to +400°F range covers everything I throw at them, and the 2.6" ID fit my application perfectly—no leaks

These o-rings handled the 350°F steam in our autoclave perfectly, no softening or swelling after a week of cycles. The 90 durometer feels noticeably stiffer than the standard 70 I'd used before, which is exactly what we needed for the high-pressure seal.

Had a small leak in a hydraulic line that was driving me nuts. These Viton rings sealed it right up on the first try, and the 90 durometer feels noticeably firmer than the standard ones I've used before. Pretty impressed with how well they handle the high heat.
