Ruby ★★★★★

I’ve been using these to seal a pressure vessel for a few weeks now, and the high heat rating gave me peace of mind near a steam line. They’re slightly firmer than the last ones I tried but hold the seal just as well.

Chloe ★★★★★

The 0.21" cross-section fits my pump's groove perfectly, and the red color makes them easy to spot during maintenance. I've used these in a steam application up to 300°F with no softening or leaks so far.

Jason W. ★★★★★

I needed replacements for a high-temp seal on a valve, and these handled the 400°F steam cycles without any softening. The red color makes them easy to spot during maintenance, and the pack of 40 is great value.
