Ella D. ★★★★★

The 75 durometer on these o-rings feels just right for my pneumatic application, and they slid into the groove with no struggle at all. I used them to seal a hot oil line, and the Viton FKM material seems to handle the 200°F temps without any signs of wear so far.

Ava ★★★★★

These are holding up perfectly on my hydraulic line that sees regular 350°F heat. The brown color made them easy to spot during installation, and the 75 durometer feels like the right stiffness for this application.

Emma ★★★★★

I needed a replacement for a high-temp application and these FKM o-rings handled the 350°F environment without any issues. The 75 durometer feels firm yet pliable enough to seat perfectly in the groove. Exactly what the specs promised.
