Finally, o-rings that actually hold up in my sous vide setup without getting brittle. The red silicone is easy to spot when I'm cleaning them, and the -80°F range gives me confidence for freezer applications too. These fit perfectly on my pressure cooker lid.

I needed high-temp seals for a lab autoclave, and these silicone o-rings handle up to 450°F without any issue. The 70 durometer gives them just the right firmness for a tight seal without being too stiff.

The bright red color makes it easy to spot during disassembly, and the 70 durometer silicone feels just pliable enough to seat firmly without tearing. These handled a 400°F bake cycle without any hardening or sticking.
