Hannah Y. ★★★★★

The 70 durometer feels just right—firm enough to seal well but not brittle like some cheaper rings. I used these for a hot water valve rebuild and they seated perfectly without any twisting or binding.

Elizabeth ★★★★★

The red color makes them easy to spot during assembly, which I appreciate when sorting through a toolbox. The 70 durometer feels flexible yet sturdy, and the temperature range gives me confidence they'll handle both hot and cold applications. Just what I needed for a custom pump rebuild.

Timothy ★★★★★

I needed a high-temp seal for a steam valve, and the 450°F silicone rating gives me total confidence. The red color actually helps me spot them quickly during maintenance.
