Madison ★★★★★

The high-temperature rating is exactly what I needed for my home brewing setup. These 5.234" ID rings sealed perfectly on my kettle lid with no leaks, and the red color makes them easy to spot.

John J. ★★★★★

I've been using these red silicone o-rings for a high-temp fluid application, and they've held up perfectly at 400°F with no signs of degradation. The 70 durometer feels just right for a secure seal without being too stiff.

Andrew C. ★★★★★

These fit perfectly on my brewing kettle's thermometer port and the red color makes them easy to spot if one falls off. The 450°F rating gives me peace of mind during boiling, and after a month of use they still feel supple with no cracking.
