Abigail K. ★★★★★

The fit on my hydraulic cylinder was perfect with these 7.725" ID o-rings, and they seated firmly without any rolling. I've been using them around 200°F lubricant and the HNBR material feels much more durable than standard Buna-N.

Lucy F. ★★★★★

The 80 durometer rating is noticeably firmer than the standard Buna seals I've used, which should hold up better in this high-heat application. I checked the ID with calipers and it's spot on at 7.725 inches across the entire package of six.

Avery ★★★★★

These replaced a worn seal in a high-temp application and the HNBR compound handles the heat that killed the old one. The 80 durometer feels firm but still seated into the groove without much fuss, and the 7.725" ID fit perfectly.
