Customer Reviews (4.8 / 5 · 5 reviews)

Owen Y. ★★★★★

The soft 12 durometer PTFE material seals perfectly in a low-torque application where harder o-rings always leaked. I've ordered a second pack since these handle high heat without any issues.

Samuel ★★★★★

Finally found an o-ring that doesn't deform under constant chemical exposure—the PTFE material holds its shape perfectly in my application. The 12 durometer feels surprisingly firm yet seals tight against the 1.049" bore without any leaks. Worth every penny for the extreme temperature tolerance alon

Benjamin V. ★★★★★

The temperature range on these is wild—I’ve got them in a valve that cycles from cryo to hot oil, and they haven’t cracked or deformed after months. The 12 durometer makes them surprisingly pliable for PTFE, which helped them seat perfectly in the groove.
