Emma D. ★★★★★

The FDA compliance was the reason I picked these for a food-processing line, and the red color actually makes them easy to spot during inspections. Took a beating at 350°F for weeks without any hardening, and the 100-count pack means I've got spares for the next rebuild.

Michael H. ★★★★★

I needed a high-temp seal for a hot oil line, and these FDA silicone o-rings handle the 450°F rating perfectly. The 2.424" inner diameter fit snugly with no leaks, and the 100-pack gives plenty of spares for future projects.

Scarlett ★★★★★

The red color makes these easy to spot in my parts bin, which saves time during assembly. Fit the 2.424" groove perfectly, and the silicone feels much more pliable than the Buna-N ones I usually use.
