Aurora U. ★★★★★

The 4.234" ID fit my flange perfectly on the first try, and the Viton's stiffness at 70 durometer feels just right for a snug seal. I torqued it down at 300°F and it hasn't leaked a drop.

Lucy ★★★★★

The cross-section on these o-rings is exactly 0.139" as listed, which made them a perfect fit for my hydraulic cylinder rebuild. They replaced a set that was only rated to 250°F, so I'm glad I went with the Viton material since this line sees continuous heat.

David D. ★★★★★

These o-rings handled a 375°F steam line repair without any softening or swelling. The 70 durometer feels just right for a snug seal without being a struggle to install.
