Sophia S. ★★★★★

The X-ring profile seats better than standard o-rings on my stubborn hydraulic fitting, and the Viton handles the 350°F oil temps without swelling. Eight in a pack means I’ve got spares for the next rebuild.

Stella A. ★★★★★

I needed a high-temp seal for a compressor rebuild and these Viton rings handled the 350°F test run without any sign of softening. The 70 durometer feels just right for a snug fit without being impossible to install.

Sophia C. ★★★★★

Finally found a set of o-rings that actually handle the high-temp applications I need, and these Viton FKM ones are holding up perfectly so far. The 70 durometer feels just right for the seal I needed, not too stiff and not too soft.
