Aurora ★★★★★

These square profile o-rings fit perfectly into the machined groove on my hydraulic cylinder, and the 70 durometer feels firm without being brittle. Nice to have a bulk pack so I don't have to hunt for the right size mid-project.

Evelyn N. ★★★★★

Finally getting around to replacing all the old square-cut seals in my shop press, and these 70 durometer Buna-N rings fit perfectly. The 500-count pack means I’ll have spares for the next few rebuilds without reordering.

Natalie ★★★★★

I needed a bulk supply for a hydraulic repair job, and these 70-durometer Buna-N rings seated perfectly with no distortion. The 0.736" ID matched the groove specs exactly, which saved me a lot of trial and error. At 500 per pack, I’ve got plenty left for future projects.
