Samuel ★★★★★

The high-temperature rating of -80°F to +450°F is exactly why I bought these for my oven door gaskets, and they’ve held up perfectly through several high-heat cycles already. The red color makes them easy to spot during installation, which is a nice bonus.

Kevin I. ★★★★★

Used one to replace a seal on a steam valve at work and it held up perfectly at 350°F, no leaks at all. The 70 durometer feels firmer than the old one but not brittle, and the red color made it easy to spot during installation. Exactly what I needed for the high-temp application.

Riley Z. ★★★★★

The color and sizing were spot on for my rebuild, and knowing these are FDA-compliant silicone gives me peace of mind for food-contact gear. Fit the groove perfectly without any wrestling, and the 70 durometer feels sturdy but not stiff.
