Harper ★★★★★

I needed a bulk pack of 90-durometer o-rings for a hydraulic seal repair job, and these Buna-N ones handled the high pressure without deforming. The pack of 600 is exactly what I needed for multiple repairs.

Henry R. ★★★★★

Put these in a high-pressure pneumatic actuator at work and they've held up perfectly for a few weeks now. The 90 durometer feels noticeably stiffer than the standard ones I used before, which is exactly what I needed.

Chloe T. ★★★★★

The dash 912 size is exactly what my hydraulic cylinder rebuild needed, and the 90 durometer feels sturdier than standard o-rings. They fit the groove perfectly, and the 600-count bag gives me plenty of spares.
