Christopher ★★★★★

These replaced the old black ones in a high-temp gasket application and they’re holding up perfectly at +400°F. The 70 durometer is exactly right for the seal I needed—not too soft, not too stiff.

Thomas W. ★★★★★

The red color makes them easy to spot when I’m digging through my toolbox, and the 70 durometer gives just the right amount of flex without feeling flimsy. I’ve used them in a few high-heat setups up to 400°F and they’ve held their shape perfectly.

Jacob U. ★★★★★

The high-temp rating is what sold me, and after sitting near a hot engine block for a week they haven't cracked or deformed. The red color also makes them easy to spot during maintenance.
