Riley ★★★★★

I needed some for a hydraulic cylinder rebuild and these AS568-215s fit perfectly, with a snug seal right out of the bag. The durometer feels just right for high-pressure applications, and having 600 in one pack means I’m set for years.

Emma F. ★★★★★

These o-rings have a nice firm feel from the 70 durometer, and the 600-count pack will last me through several rebuilds. I used a few on a small hydraulic cylinder and they sealed perfectly first try, even at 200°F.

Ava F. ★★★★★

The 0.139" cross-section fit perfectly in my hydraulic fitting where thinner rings kept failing. I've installed a dozen so far and each one seated cleanly without any distortion. These are exactly what I needed for a reliable seal in moderate heat applications.
