Eli E. ★★★★★

I needed AS568-129 o-rings for a hydraulic cylinder rebuild, and these fit perfectly with that 1.549" ID. The 70 durometer seals well without being too stiff, and the bulk pack of 600 will last me through multiple jobs.

Emily C. ★★★★★

Just swapped out an old seal on a hydraulic unit and these 129 o-rings were a perfect match. The 70 durometer feels plenty firm, and the package of 600 should last me for years.

George Z. ★★★★☆

The 70 durometer feels just right for my pneumatic fittings—firm enough to seal without being a pain to install. The pack of 600 means I won't be reordering for a while, though the bag they came in could be sturdier.
