Mia ★★★★★

The temperature range on these is what sold me—handling -80°F to 450°F means they'll survive both my freezer gasket and the hot water line without cracking. They fit snugly and the red color makes them easy to spot during disassembly, which is a nice bonus.

Ryan D. ★★★★★

I needed a high-temp seal for my pressure cooker and these red rings fit the groove perfectly; the 70 durometer felt solid but not too stiff. They slipped right on with no stretching issues, and the 16-pack is great to have extras.

Andrew ★★★★★

These sealed perfectly on my commercial steamer's gasket where the old ones kept failing. The high-temp silicone handles the 300°F steam cycles without getting brittle.
