Violet K. ★★★★★

Used these AS568-111 Viton o-rings to replace some old rubber ones in a valve that sees steam up to 300°F, and the 400°F service range gives me peace of mind. The 75 durometer feels firm but still seats easily without tearing. So far no leaks after a month of daily use.

George ★★★★★

Installed these in a hydraulic press that regularly sees temps above 300°F, and they’ve held up perfectly for two months now. The 75 durometer feels firm but not brittle, and the 0.424" ID was a spot-on fit for the groove.

Penelope ★★★★★

The dash 111 size was exactly what I needed for a stubborn hydraulic fitting, and the 75 durometer gives a nice firm seal without being too rigid. I've used cheaper o-rings that went brittle after a few heat cycles, so the Viton FKM material here feels like a solid upgrade for the money.
