Grace ★★★★★

The temperature range is what sold me—my application fluctuates between cryogenic and hot, and these PTFE rings haven’t cracked or deformed in three months of cycling. The 1.986" ID fit my groove perfectly on the first try, and the 13 durometer gives them just enough give to seat without squishing o

Sofia I. ★★★★★

I needed a seal that could handle extreme temperatures, and these PTFE o-rings work perfectly in my cryogenic setup. The 13 durometer is soft enough to seat without leaking.

John N. ★★★★★

These o-rings handled the extreme heat in our industrial oven much better than the standard rubber ones we tried before. The PTFE material feels dense and well-formed, exactly the right size for our application.
