Customer Reviews (4.8 / 5 · 5 reviews)

Brian W. ★★★★★

Installed these on a valve housing that sees constant heat cycles and they’ve held their shape perfectly. That 450°F rating gives me peace of mind in a high-temp line.

Avery E. ★★★★★

I needed a tight seal for a steam table insert, and the 7.984-inch ID fit perfectly with no gaps. The red silicone feels flexible but sturdy, and the 70 durometer handles the heat without softening.

Charlotte J. ★★★★★

The high temperature rating was exactly what I needed for my kiln door seal, and the red color makes them easy to spot against the metal frame. These fit snugly with no binding on the 8-inch diameter pipe.
