Evelyn ★★★★★

These fit perfectly in our compressor rebuild, and the 90-durometer HNBR holds up well under the constant heat. Much better than the standard Buna-n I tried before.

Sofia K. ★★★★★

Been using these in a high-temp compressor application and the -40°F to +300°F rating is spot on—no leaks even after thermal cycling. The 90 durometer gives a nice firm feel during installation, too.

Sofia W. ★★★★★

The seal fit perfectly into a hydraulic cylinder I rebuilt for a log splitter, and the 90 durometer has held up great under pressure. It arrived well-packaged and the 2.984-inch inner diameter was right on the money.
