Customer Reviews (4.6 / 5 · 5 reviews)

Victoria ★★★★★

The temperature range listed on these is wild, so I’m not worried about them melting in my hot oil setup. The 13 durometer makes them soft enough to seat firmly without splitting, and the package of 35 covers me for multiple rebuilds.

Penelope Y. ★★★★★

I needed a soft seal for a high-temp chemical line, and these 13 durometer rings compressed just right without cracking at 450°F. The package of 35 was more than enough for my test rig.

Claire ★★★★★

These o-rings handled a cryogenic fitting test without any issues, way down at liquid nitrogen temps. The 13 durometer PTFE is impressively stiff but seals perfectly in the groove.
