I’ve been using these o-rings for a high-heat application, handling up to 450°F without any softening. They slipped into the groove easily, and the 70 durometer gives a great seal that holds pressure well.

The 70 durometer feels just right for my steam table gasket—firm enough to seal but still pliable. These red silicone rings handled the 400°F preheat cycle without any degradation. Exactly what I needed for that high-temp application.

I needed a precise 19.475" ID ring for a high-temp process line, and these fit perfectly without any stretching or binding. The red color makes them easy to spot during maintenance checks, and they've held up well under constant 300°F exposure.
