Olivia P. ★★★★★

I needed a reliable seal for a high-temp application and these silicone o-rings handled the range perfectly, from sub-zero to over 400°F without any degradation. The red color makes them easy to spot during assembly, which is a nice bonus.

William Y. ★★★★★

Took a chance on these for a high-temp beverage line application, and the silicone handles the steam nicely. The 70 durometer feels just right—firm enough to seal but still pliable to install. I've used them in a range from cold rinse to boiling water with no issues.

Scarlett ★★★★★

These red o-rings fit perfectly in my homebrew kettle lid, and the 70 durometer silicone feels durable but not too stiff. I'm glad they're FDA compliant since they touch hot liquid, and the 0.21" cross-section makes a solid seal without leaking.
