Eli C. ★★★★★

The 70 durometer feels just right for our hydraulic fittings, and the 400-count package means enough spares for the whole job. We've had them in a steam line at 200°F for two weeks now with zero leaks.

Ella Q. ★★★★★

The square profile on these o-rings seats perfectly in my hydraulic fittings, no rolling or twisting during installation. The 70 durometer buna-n feels durable yet pliable, and the batch count of 400 should last me through multiple projects.

Evelyn ★★★★★

These square profile o-rings fit perfectly in my pneumatic cylinder rebuild. The 70 durometer feels firm but not too stiff, and they sealed the air lines on the first try without any leaks.
