Henry ★★★★★

I needed o-rings that could handle repeated heat cycles in my smoker, and these red silicone ones take the 450°F without any issue. The 70 durometer feels exactly right for a snug seal without being too stiff.

Julian S. ★★★★★

Went looking for a higher-temp replacement for my worn-out seals and these definitely deliver. The 450°F rating means no worries near the engine block, and the package of 11 gives me plenty of spares for future jobs.

Aurora Y. ★★★★★

The red color makes them easy to spot during assembly, and the 70 durometer has a nice firm feel without being brittle. I've used these in a hot water application around 200°F with no issues at all.
