Kevin A. ★★★★★

I was replacing the seals on a high-temp valve and these red silicone o-rings slid right into place without any binding. The 70 durometer feels just right for my application, and knowing they're FDA compliant gives me peace of mind for food-grade equipment.

Adam H. ★★★★★

The rubber feels pliable yet firm enough to hold a solid seal, and the 70 durometer handles the heat from my autoclave cycles without any warping. Threw them in a hot oil test at 400°F and they didn't lose shape or get brittle after an hour.

Violet Q. ★★★★★

I use these for high-temp sealing in my shop, and they've held up great with no cracking after repeated heat cycles. The -80°F to +450°F range is spot on for what I need, and the 70 durometer gives them just the right firmness for a snug fit.
