David F. ★★★★★

These 90-durometer HNBR rings feel noticeably firmer than the standard Buna ones I've used before, which is exactly what I needed for a high-temp seal. They slipped onto the flange without tearing and seated perfectly, so the whole job took maybe ten minutes.

Abigail E. ★★★★★

The 1.984" inner diameter fit my housing perfectly on the first try, no wrestling or stretching needed. I've got them holding up in an engine bay that regularly sees 250°F, and the 90 durometer feels like they'll outlast the equipment.

Eva Q. ★★★★★

The 90 durometer on these o-rings makes them feel much more durable than standard nitrile, and they fit perfectly in my hydraulic assembly. Slipped right into the groove without any distortion, and I’m confident they’ll hold up under the heat.
