Natalie O. ★★★★★

Needed to replace a high-heat seal in my compressor and these Viton FKM rings handled the 350°F running temp without any softening. The 3.359" ID was a spot-on fit for the groove.

Jacob ★★★★★

The 90 durometer rating on these o-rings gave me confidence for a high-pressure steam line repair, and they sealed perfectly on the first try. Even with the temperature cycling up near 350°F, they've held without any leaks for two weeks now.

Matthew U. ★★★★★

Put these on a hydraulic fitting that sees constant 200°F oil, and they've held up perfectly for months now without any sign of hardening or cracking. The 35-count package gives me plenty of spares for the price.
