Henry X. ★★★★★

The high-temp rating on these o-rings is perfect for my steam distillation setup, and the red color makes them easy to spot during installation. They fit snugly and the silicone feels durable. Exactly what I needed.

Stella ★★★★★

I needed a food-grade seal for my hot water bath setup, and these red silicone o-rings fit the 9.725" ID perfectly with no slipping. The 70 durometer feels firm but not brittle, and they went on smoothly without any prying.

David Z. ★★★★★

The -80°F to +450°F range is why I grabbed these, and they’ve been sitting in a steam line without any softening after two weeks. The red color also makes them easy to spot when I’m digging through my seal bin.
