حلقات O من HNBR بقطر داخلي 0.799" وقطر مقطع 0.103" | AS568-117 | داش 117 | صلابة 70 (100/عبوة)

These HNBR o-rings fit perfectly into my pneumatic actuator rebuild, and the 70 durometer feels just right for the pressure I'm running. The tight tolerance on the 0.799" ID means no leaks after a week of cycling.

I’ve been using these in a hydraulic application where other o-rings kept failing, and the snug fit of the 0.799" ID with the 0.103" cross-section has held up perfectly under constant heat. They seat easily without twisting or deforming, and after a few weeks of operation, there’s zero sign of harde

The high-temp rating was the main reason I picked these, and they're holding up perfectly in my engine bay where standard nitrile always failed. Seals tight with no leaks so far, and the pack of 100 gives me plenty of spares for future projects.
