Edward V. ★★★★★

The 70 durometer rating is perfect for my hydraulic cylinder rebuilds, providing a solid seal without being too stiff. These AS568-227 rings fit precisely on the 2.109" ID groove, and the 300-count package means I've got plenty for future repairs.

Grace O. ★★★★★

The 70 durometer hardness is just right for my application—firm enough to seal firmly without fighting me during installation. These are also the first o-rings I've bought that came neatly packaged in a resealable bag, which makes storing the leftovers for the next job much less messy.

Eva ★★★★★

Needed a reliable seal for a hydraulic cylinder rebuild, and these dash 227s fit perfectly. The 70 durometer feels just right—firm enough to hold pressure but not too stiff to seat easily. A solid 300-count bag means I’ve got plenty for future repairs.
