Customer Reviews (5.0 / 5 · 5 reviews)

Claire ★★★★★

These have handled both boiling water and a hot engine bay without losing their shape, which the cheap ones never did. The red color makes them easy to spot when I drop one, and the 70 durometer feels firm but not brittle.

Abigail ★★★★★

Finally found o-rings that can handle extreme temperatures without cracking; the -80°F to +450°F range is exactly what my project needed. The 70 durometer silicone feels firm yet flexible enough for a snug seal.

Robert N. ★★★★★

I needed o-rings for a hot water application, and the 450°F rating on these gives me peace of mind. They fit the groove perfectly, and the red color makes them easy to spot during installation.
