Amelia K. ★★★★★

Needed a reliable seal for a steam line that hits over 300°F and standard Buna-N was failing fast. These FKM rings handled the install perfectly and the 90 durometer feels solid. Exactly what the application required.

Hannah T. ★★★★★

Installed these in a high-temp hydraulic fitting that kept leaking with standard Buna-N; the Viton sealed it perfectly right away. The 90 durometer feels sturdy without being hard to work into the groove. Exactly what I needed for the 400°F range.

Steven ★★★★★

These 90-durometer Viton rings handled my hydraulic fitting's heat cycle perfectly without any creep. The 1.609" ID was exactly right for the shaft, and they seat firmly without twisting during installation.
