Matthew ★★★★★

Installed a pair of these on a hot oil line that kept failing with standard Buna rings—the Viton FKM handles the 350°F operating temp without any softening. They seated perfectly in the groove with no twisting. So far zero leaks.

Mia ★★★★★

Had a stubborn hydraulic cylinder leak that these o-rings fixed on the first try. The Viton material stands up well to the heat and pressure, and the 75 durometer rating gave a solid seal without being too stiff.

Ryan X. ★★★★★

These fit perfectly on my air compressor filter housing where standard Buna-N rings kept failing from the heat. The 75 durometer feels just right for sealing, and the brown color makes them easy to spot against black metal.
