Avery G. ★★★★★

Took a chance on these for a high-heat application and the -80°F to +450°F range is exactly why I bought them. The red silicone feels dense and quality, and the 9.484" ID fits my flange perfectly with no stretching or deformation.

Natalie X. ★★★★★

The 0.139" cross-section on these seals is noticeably more forgiving than the hard rubber ones I'd been using. They slipped right into the groove on my steam kettle and held pressure perfectly during the first test at 350°F. This pack of eleven should last me through quite a few maintenance rounds.

Victoria X. ★★★★★

Finally found a silicone o-ring that can handle my high-temp brewing setup. The 0.139" cross-section fit perfectly into the groove, and the bright red color makes it easy to spot during cleaning.
