Benjamin ★★★★★

Had a leak in a high-temp line that kept coming back with standard rubber rings. These Viton FKM o-rings have held up perfectly so far, even with the engine running at full operating temperature. The 75 durometer feels firm but seals nicely.

Claire R. ★★★★★

Wasn't sure about spending the extra on Viton FKM but the 400°F rating gives me peace of mind for my engine application. These brown 433s seated perfectly and feel much more substantial than standard Buna-N rings I've used before.

Scarlett ★★★★★

Finally got around to replacing the seals on a high-temp steam valve and these Viton FKM o-rings handled the 400°F rating without any issues. The 75 durometer feels just right for a snug fit without being too stiff.
