Aurora ★★★★★

The red color makes them easy to spot when I'm digging through my spare parts bin, which is a nice touch. They slid onto the fitting without any struggle and sealed perfectly the first time, so the 70 durometer feels just right.

Eva Q. ★★★★★

The temperature range on these is what sold me—I’ve got them in a steam line that hits 400°F and they haven’t softened or cracked after a month. The 70 durometer feel is also just right for a snug seal without being a nightmare to install.

Emma ★★★★★

The FDA-compliant silicone is a huge plus for my food processing setup, and the 70 durometer feels just right for a snug seal without being a pain to install. These red rings handled a hot steam line all week without any warping, which is more than I can say for the last ones I tried.
