Ava ★★★★★

The square profile makes these seat way better in my hydraulic fittings than round o-rings ever did, and the 70 durometer gives just the right firmness without crushing. I've used maybe fifty so far and every one seated perfectly with no deformation, even at 200°F on the pump housing. Nice to have t

Thomas ★★★★★

Finally got my hands on a full thousand-count bag of these AS568-111 square cuts — the 70 durometer feels just right for my hydraulic seals. They slipped into the grooves without any struggle, and I'm confident they'll hold up well in the -40°F range we see in the shop.

George A. ★★★★★

The square profile on these o-rings sits perfectly in the groove without rolling, which has been a constant headache with standard rounds. I'm about 300 seals into a pneumatic rebuild and haven't had a single leak. For the price per thousand, these are a steal for any hydraulic application.
