Matthew ★★★★★

These o-rings fit perfectly into a high-temp brewery valve on my wort chiller. The bright red color also makes them easy to spot if they fall during assembly.

Jason ★★★★★

Replaced two leaky gaskets in my home water filter housing with these, and the red color makes them easy to spot during disassembly. The -80°F to +450°F range gives me confidence they'll hold up in both my freezer line and the hot side. Fit was snug and precise at 3.109" ID.

Grace ★★★★★

The 70 durometer is just right for my high-temp filtration setup—no leaks at all since I installed them. These red silicone rings held up perfectly through a 400°F sterilization cycle.
