Chloe ★★★★★

I was a bit skeptical about the red color, but these o-rings handle high heat beautifully in my sous vide setup. The 70 durometer feels just right—firm enough to seal without being too hard to install.

Charlotte K. ★★★★★

The 0.912" inner diameter fits perfectly on my brewing kettle's lid, and the silicone feels solid yet flexible. I've had them in a steam environment for weeks with no sign of wear.

Ryan ★★★★★

I needed a high-temp seal for a hot water valve rebuild, and these silicone rings handle up to 450°F without any issue. The 70 durometer is firm enough to hold, and the 0.912" ID fit perfectly on my first try.
