Claire M. ★★★★★

Kept a few extras in the glovebox for a stubborn transmission leak, and the 0.546" inner diameter was spot-on for the fitting. These Viton rings handled the heat without swelling, which is more than I can say for the last batch I tried.

Thomas ★★★★★

The 75 durometer feels like a perfect middle ground for my hydraulic fittings—not too stiff, not too soft. I installed a few in a hot water valve and they seal perfectly at 190°F without any leaking.

Ryan O. ★★★★★

Installed these in a hydraulic pump that sees frequent 200°F oil, and the Viton material held up perfectly without any softening. The 0.139" cross-section fit snugly into the groove. Very pleased with the consistent quality across all 75 rings.
