Victoria ★★★★★

Had to replace some aging seals on a chemical transfer pump, and these 70 durometer EPDM rings fit the 4.734" groove perfectly. They're handling the occasional hot water flush up to 300°F without any softening or leaks so far.

Madison R. ★★★★★

Installed a set on a steam line that sees about 280°F and they sealed up tight first try—no leaks at all. The 0.139" cross-section feels thicker than cheaper ones I've used before.

Joshua N. ★★★★★

Needed these for a hot water recirculation project and the 4.734" ID was exactly what I needed for the flange. The EPDM material is holding up great against the heat so far.
