James H. ★★★★★

The 0.21" cross-section is thick enough that these rings don't twist when I slide them into the groove. They fit perfectly on my filter housing, and that high-temp rating gives me peace of mind for hot water applications.

Kevin B. ★★★★★

The high-temp range on these rings is perfect for my hot water circulation pump; they seat well and show no signs of hardening after a month of use. The red color also makes them easy to spot during maintenance.

Ava Y. ★★★★★

These sealed perfectly on a high-temp food processing valve we rebuilt; the 70 durometer silicone is firm enough to hold pressure but still easy to seat. I've had issues with cheaper o-rings softening at our steam temps, but these have held up great so far.
