Ryan ★★★★★

Finally, an o-ring that doesn't crack after a season of hot oil exposure—the 400°F rating is no joke. The brown color made them easy to spot on the workbench, and the 75 durometer feels firm yet forgiving during installation. These fit my 3.489" bore perfectly on the first try.

Steven ★★★★★

I needed a high-temp o-ring for a hydraulic fitting on a baking press, and these Viton ones seated perfectly with no leaks. The 75 durometer feels sturdy but not too stiff.

Claire S. ★★★★★

These Viton rings handled 350°F steam in my autoclave without any softening or cracking. The 0.07" cross-section seated perfectly in the gland groove.
