Timothy ★★★★★

Swapped out a worn-out seal in a cryogenic test rig and these PTFE rings seated perfectly without any deformation. The -350°F rating gives me confidence they’ll hold up where standard rubber would shatter. Just wish they came in smaller quantities, but the 50-pack is a fair deal for the price.

Eli ★★★★★

Pressing these into a tight groove was tricky at first because they're so stiff, but once seated they seal perfectly on my high-temp valve. The 11 durometer feels almost like hard plastic, which is exactly what I needed for the -350°F cryogenic application.

John ★★★★★

The temperature range is the real selling point here—I've pushed them down to near -300°F without any cracking or hardening. The 11 durometer rating means they're surprisingly flexible for PTFE, which made installation onto the groove a breeze. Fifty in the pack gives me plenty of spares for future
