Customer Reviews (4.8 / 5 · 5 reviews)

Emily ★★★★★

The red color makes them easy to spot against dark fittings, and the 70 durometer feels just right for my plumbing project. They sealed the valve perfectly on the first try, saving me from a frustrating leak.

Penelope ★★★★★

The temperature range on these is the real selling point for me—I’ve got them in a hot manifold setup that hits 380°F and they’ve held their seal perfectly. The red color also makes them easy to spot during inspection. Just wish they came in smaller quantities, but 400 will last me years.

Jacob Z. ★★★★★

I've used these for a custom gasket on a hot water line that hits 200°F, and they haven't softened or leaked at all after a month. The 70 durometer feels just right for a snug seal without being too hard to work into the groove.
