Mia W. ★★★★★

I needed a bulk pack for a hydraulic repair job, and these square-profile rings seated perfectly in the groove without rolling. The 70 durometer feels just right for the pressure range I'm working with.

Joseph ★★★★★

The square profile on these o-rings seals much better in our hydraulic fittings than the round ones we used before, and the 70 durometer feels just right for the pressure. Having 400 in a pack means I won't run out mid-job again.

Andrew ★★★★★

Needed a full box of AS568-211s for a pneumatic repair job, and the 70 durometer is just right—not too stiff, not too squishy. The square profile seats perfectly in the gland without rolling out, which saved me a lot of hassle during installation.
