David L. ★★★★★

The 14.975" inner diameter fit my flange perfectly on the first try, and the 70 durometer feels sturdy yet flexible when stretched into place. I've used cheaper o-rings before that hardened after a few heat cycles, but these held up fine at 300°F in my setup. The red tint is a nice bonus for quick v

Nicholas ★★★★★

The red color makes them easy to spot during assembly, which saved me time when checking the seal on a big flange. The 70 durometer feels firm yet flexible, and they slipped into the groove without any twisting or rolling.

Joseph N. ★★★★★

These are holding up perfectly in a high-temp steam application where cheaper seals failed in weeks. The 70 durometer gives them enough flex to seat easily without being floppy. Great fit on a 15-inch flange.
