Amelia ★★★★★

I was replacing old gaskets on a hot water valve and these red silicone rings held up perfectly at 350°F without any softening. The 70 durometer feels just right, not too stiff.

Thomas N. ★★★★★

The -80°F to +450°F range is exactly what I needed for a steam line at work, and the red color makes them easy to spot during inspection. They’re firm at 70 durometer, not flimsy, and all fifty arrived without any deformation.

Ava N. ★★★★★

Installed these on some hot water plumbing I’ve been fixing and the 70 durometer feels just right for a snug seal without being hard to work into place. The red color also makes them super easy to spot when I drop one on the floor.
