Ryan ★★★★★

After a dozen failed attempts with cheaper o-rings, these 90 durometer Buna-N seals finally stopped the high-pressure air leak in my pneumatic cylinder. The AS568-140 dimensions were spot on for the groove depth, and the package of 300 will last me years.

Ruby F. ★★★★★

The 90 durometer on these is perfect for my hydraulic repair kit—they seat firmly without deforming under pressure. The temperature range covers everything I need in the shop, from cold starts to hot oil. A solid value for a bulk pack of 300.

Leo ★★★★★

I needed these for a high-pressure hydraulic repair, and the 90 durometer holds up much better than the standard 70 I’ve used before. The pack of 300 was delivered quickly, and every ring I’ve installed so far seals perfectly without any visible flaws.
