Sebastian T. ★★★★★

Bought these for a hot water valve rebuild and they sealed perfectly on the first try, no leaks at all. The red color makes them easy to spot against the metal fittings, and the 70 durometer feels just rigid enough to hold their shape during installation.

Riley V. ★★★★★

The high temp rating was exactly what I needed for my smoker mod, and the red color makes them easy to spot during assembly. Pack of 70 should last me years.

Brian ★★★★★

Just swapped out a worn seal on my espresso machine with these FDA-compliant red rings, and the fit was spot-on for the 1.287" ID. The 70 durometer feels firm enough to hold pressure but not too stiff to install.
