Samuel ★★★★★

These seals handled the -350°F spec perfectly for a liquid hydrogen test rig I built. The 12 durometer PTFE is surprisingly supple compared to standard Teflon, making installation much easier.

George R. ★★★★★

The temperature range is what sold me, and so far these PTFE rings have handled a brutal -300°F cold test without any cracking or loss of seal. They're stiff as expected for 12 durometer, but that's exactly what I needed for a static joint.

Ava L. ★★★★★

Fitting these into the groove took a bit of patience since they're so soft, but the -350°F rating gives me total peace of mind for the cryo test rig I'm building. They seat beautifully and haven't deformed after a week of cycling.
