Ava T. ★★★★★

These red silicone o-rings fit my pressure cooker valve perfectly—the 0.21" cross-section is exactly what the manual called for. They feel sturdy and the bright color makes them easy to spot during cleaning.

Eva ★★★★★

I needed these for a high-heat gasket application and the 70 durometer silicone handled the constant 400°F exposure without any shrinkage. The bright red color also makes them easy to spot during maintenance checks.

Andrew ★★★★★

Installed these on a couple of large mixing vats and the 70 durometer feels just right—firm enough for a good seal but still pliable. The red color makes them easy to spot during maintenance. They showed no issues after a few cycles up to 400°F.
