Customer Reviews (4.8 / 5 · 5 reviews)

Ryan Q. ★★★★★

The red color made them easy to spot during assembly, which I appreciated. The 70 durometer hardness feels just right for a snug fit without being impossible to install.

Aurora ★★★★★

The temperature range on these is what sold me—I've used them in a hot oil bath at 400°F and they haven't degraded or hardened at all. The red color makes them easy to spot on the bench, and the 150-count pack means I won't run out for a while.

Sophia X. ★★★★★

These fit perfectly on my homebrew kettle's thermometer probe, and the red color makes them easy to spot if one pops off. The 70 durometer feels firm enough to create a reliable seal at boiling temps.
