Hazel A. ★★★★★

These rings fit perfectly on a vacuum port that sees constant 300°F heat, and the 70 durometer feels just right—not too stiff to install but firm enough to hold its seal. I’ve had zero leaks since putting them in.

Miles ★★★★★

Used one to replace a leaking seal on a hot oil line that was running around 200°F, and it hasn't leaked a drop since. The 70 durometer feels just right for this application.

Adam ★★★★★

The silicone-free Viton material handles heat way better than the standard rubber rings I’d been using, and the 1.234" ID fit my fitting perfectly. Pack of 30 means I’ve got spares for the next few rebuilds, and the 70 durometer feels firm without being brittle.
