Henry ★★★★★

The AS568-232 size fits my old pump housing perfectly, and the 70 durometer hardness feels right for the pressure I’m running. A full pack of 250 means I won’t have to reorder for a while, which is a nice bonus.

Claire G. ★★★★★

I've been using these o-rings for a hydraulic repair job and the 70 durometer feels just right—not too stiff, not too soft. The package of 250 is generous for the price, and they seated perfectly in the groove without any distortion.

Ruby ★★★★★

The 0.139" cross-section on these is just right for the hydraulic cylinder I rebuilt — fit snugly without being a struggle to seat. Used about half the bag and every ring was clean, no flash or imperfections. Glad I bought the 250 pack instead of counting out individual ones.
