Grace ★★★★★

These o-rings held up perfectly in a high-heat gasket repair on my smoker, even after hours at 400°F. The 70 durometer feels just right—firm enough to seal but flexible enough to seat easily.

Steven ★★★★★

The metal detectable feature gives me peace of mind in our food processing equipment where contamination is a real concern. These silicone o-rings fit perfectly in our steam table, and the -80°F rating handles our freezer applications without getting brittle. Exactly the high-temp solution I needed.

Miles V. ★★★★★

I needed a high-temp seal for an oven door and these silicone o-rings handle the 450°F range without any issue. The 7.984" ID was spot-on for my application, and the metal-detectable feature gives me peace of mind for food processing.
