Leo G. ★★★★★

I needed FDA-grade seals for a hot water line, and these handle the -80°F to +450°F range with no issue. The 70 durometer feels just firm enough to hold pressure without being a struggle to install.

Grace Q. ★★★★★

These 70 durometer o-rings seated perfectly in my homebrew kettle's lid, and the red color makes them easy to spot during cleaning. The silicone feels robust and hasn't deformed after a few boiling sessions. Exactly what I needed for a high-temp seal.

Carter ★★★★★

The red color makes them easy to spot during assembly, which is a nice touch. They fit the AS568-336 spec perfectly, and the 70 durometer feels firm but not brittle when I stretch them over a fitting.
