Victoria O. ★★★★★

The square profile on these o-rings seals perfectly in my hydraulic fitting—much better than the standard round ones I've used before. The 70 durometer feels just right, not too stiff or soft, and the pack of 110 will last me through multiple projects.

Jacob Y. ★★★★★

Got a pack of these 0.139" cross-section o-rings for a pneumatic cylinder rebuild and they sealed perfectly on the first try. The 70 durometer feels just right for the application.

Robert ★★★★★

The square profile on these AS568-230 o-rings sealed perfectly in a groove where round ones kept slipping out. At 70 durometer they're firm enough for a tight fit but still easy to install by hand.
