Benjamin K. ★★★★★

The -80°F to +450°F range is why I picked these, and they’ve held up perfectly on a steam line that gets way too hot for standard rubber. The red color also makes them easy to spot during inspection, which is a nice bonus.

Harper B. ★★★★★

The red color makes these o-rings easy to spot during assembly, and the 70 durometer silicone feels just right for our food-grade application. They fit the groove perfectly on the first try.

Kevin H. ★★★★★

I use these for a high-temp industrial water valve that kept leaking, and the red silicone has held up perfectly in the 300°F range for months now. The FDA compliance was a nice bonus, since the same o-ring also fits a food processing line I service.
