Charlotte I. ★★★★★

These 90-durometer o-rings held up perfectly for the seal on my pneumatic cylinder, handling the constant pressure without any visible wear. The -40°F temperature rating is exactly what I needed for outdoor equipment use.

Kevin X. ★★★★★

My hydraulic press has been blowing out cheaper o-rings, but these 90-durometer Buna-N ones are holding up perfectly under high pressure. The 200-pack is a solid deal for the quality, and they fit the groove on my AS568-230 flange like a glove.

Chloe ★★★★★

I needed a bulk pack of these AS568-230 o-rings for rebuilding an old hydraulic cylinder, and the 90 durometer feels just right for the pressure. The 2.484" ID fit perfectly over the groove with no stretching issues.
