Scarlett L. ★★★★★

These 50 o-rings fit the hydraulic cylinder on my tractor perfectly; the 70 durometer is exactly what the manual specified. I replaced a worn seal and the leak stopped immediately. Good value for getting a full pack of this size.

Emma ★★★★★

The ID measured spot-on at 8.975 inches with my calipers, and the -40°F rating gives me confidence for the outdoor hydraulic lines I’m sealing. Fifty in the pack means I’ve got spares for the next rebuild, which is exactly what I wanted.

Leo I. ★★★★★

The 70 durometer feels just right for my hydraulic cylinder rebuild—not too hard to seat but plenty firm once installed. They fit perfectly into the groove without any binding, and the package of 50 gives me spares for the next job.
