George ★★★★★

I’ve been running these o-rings through repeated steam cycles near 300°F and they’re holding up perfectly, no hardening or cracking. The 70 durometer feels just right for a snug seal on my fittings, and the FDA compliance is a bonus for my food-safe setup.

Madison ★★★★★

The red silicone really pops, making them easy to spot in my toolbox. These 70 durometer rings fit perfectly on my valve stems and handle the heat from my sous vide setup without issue.

Robert F. ★★★★★

I needed high-temp seals for a lab setup, and these silicone o-rings handle up to 450°F without any issue. The 70 durometer feels firm but still seals well on my glass connectors.
