Riley X. ★★★★★

The temperature range really sold me—I’ve got a kiln door that sees constant 400°F swings, and these red ones haven’t cracked or stiffened after a month of daily use. The 8.7-inch inner diameter fit my flange like it was custom-made, and the 70 durometer gives just enough give for a snug seal.

Amelia Y. ★★★★★

These o-rings fit perfectly on my pressure cooker lid, and the 70 durometer feels firm enough to hold a good seal. The 8.734" inner diameter was exactly right for my application. They handle high heat without any issues.

Andrew ★★★★★

The red color makes them easy to spot on the workbench, and the 70 durometer silicone is pliable enough to seat perfectly in the groove. They’ve held up fine on my hot water line so far, handling the temperature range just as advertised.
