Customer Reviews (4.4 / 5 · 5 reviews)

Elizabeth Y. ★★★★★

These fit the old gauge on my steam table perfectly, even with the constant heat. The 70 durometer feels just right—firm enough to hold pressure but not brittle. Much better than the last batch of mixed rubber I tried.

Kevin ★★★★★

I was worried these wouldn't seal my hot water tank, but the -80°F to +450°F range handles the heat perfectly. The red color makes them easy to spot against the metal flange, and they fit snugly without any leaks.

Edward X. ★★★★★

The 70 durometer is perfect for my application needing a firm seal without being brittle, and the high temp range gives me peace of mind. The red color makes them easy to spot during assembly too.
