Christopher R. ★★★★★

These seals handled the full 400°F test cycle in my application without any softening or leaks. The 90 durometer gives them a solid, durable feel that smaller sizes just don't have.

Isabella M. ★★★★★

The 90 durometer hardness is exactly what I needed for a stubborn seal that kept deforming with softer rings. I've used about 50 so far and every single one has seated perfectly without any cutting or tearing. At 800 per pack, this will last me years of projects.

Harper ★★★★★

Popped a few on a high-temp steam line that’s been eating standard Buna-N rings alive, and these Viton FKM ones handle the 400°F range without any sign of softening. The 90 durometer feels noticeably stiffer than the usual 70, which is exactly what that joint needed.
