حلقات O من Viton FKM 0.103" CS × 0.799" ID | AS568-117 | داش 117 | مقطع مربع | صلابة 70 (100 / عبوة)

The square profile on these seals sits snugly in the groove without rolling, and the Viton handles the heat way better than the standard rubber ones I've used. I stocked up knowing the 100-pack would last me a while, and so far every ring has held up perfectly under constant 300°F exposure.

These square-profile o-rings sealed perfectly in my hot oil line, and the 0.799" inner diameter was exactly as measured. The 70 durometer feels firm but not brittle, and the -15°F to +400°F range covers everything I need.

I needed a high-temp seal for a hydraulic fitting, and these 70-durometer Viton rings handled the 350°F fluid without any issue. Just wish the package came with a few extras for the price.
