Isabella ★★★★★

The temperature range is exactly what I needed for a high-heat sealing application, and these o-rings fit perfectly without any deformation. They’re stiff but seal tightly in the groove.

Adam M. ★★★★★

Finally found o-rings that can handle both extreme heat and cold without degrading. These PTFE ones sealed perfectly on my high-temp valve, and the 0.103" cross-section fit snugly.

Stella S. ★★★★★

Was a bit worried about getting the right fit for a stubborn vacuum seal, but these Dash 126 rings dropped right in with zero fuss. The 12 durometer feels noticeably firmer than standard rubber, exactly what I needed for the high-temp cycling.
