Ella H. ★★★★★

Needed a replacement for a high-temp hydraulic seal and these Viton rings held up perfectly at 350°F. The 75 durometer feels firm enough to seal without being hard to install, and the 4.1" inner diameter was spot on for my application.

Owen J. ★★★★★

Installed these on a pump shaft handling hot oil and the 75 durometer FKM held up perfectly at 350°F where Buna-N used to fail. No leaks so far after two weeks of constant heat cycles.

Ruby A. ★★★★★

Was a perfect fit for my hydraulic press rebuild, the 75 durometer feels just right. These Viton rings tolerate heat way better than the standard Buna ones I tried before. Glad I went with this spec for the application.
