Customer Reviews (4.6 / 5 · 5 reviews)

Eva ★★★★★

I've been using these PTFE o-rings in a high-temp industrial application, and they've held up perfectly at 400°F without any softening. The 12 durometer is surprisingly pliable yet firm enough to maintain a good seal.

Victoria Q. ★★★★★

The extreme temperature range on these is exactly what I needed for a high-heat seal application. They slid into the groove perfectly and the 12 durometer PTFE feels surprisingly compliant.

Scarlett ★★★★★

Finally found o-rings that can handle the heat where I need them, and these PTFE ones are perfect for my high-temp application. The 12 durometer is just right—firm enough to hold a seal but not brittle.
