Sophia ★★★★★

After fighting with some softer ones that kept popping out of the groove, these 90-durometer o-rings held firm and sealed perfectly on the first try. The 2.1" inner diameter was spot-on for the application I needed.

Ryan ★★★★★

These 90-durometer rings are noticeably stiffer than the standard ones I've used, which is exactly what I needed for a higher-pressure seal. The 2.1" inner diameter fit my application perfectly, and the pack of 125 should last me for years.

Kevin ★★★★★

Finally found the right size for my old hydraulic cylinder—the 2.1" ID fits perfectly and the seal is solid under pressure. The bundle of 125 is way more than I needed but great value for the price.
