Chloe ★★★★★

Had a stubborn hydraulic leak on an old press that needed something tougher than standard o-rings, and the 90 durometer on these was exactly right. For the price of a bulk bag, I've got enough to reseal several more machines without worrying about heat failure.

Daniel W. ★★★★★

These are my go-to for high-temp seals now. The 90 durometer hardness handled the pressure in my hydraulic setup without any deformation, and the -40°F rating gives me peace of mind for winter use. A thousand of them in one box is a decade's worth of spares.

Elizabeth ★★★★★

These o-rings handled the hydraulic oil in my press perfectly, no swelling at all after a week of use. The 90 durometer feels noticeably stiffer than standard ones, which is exactly what I needed. A solid buy for the price.
