Sebastian M. ★★★★★

Finally found the right size for a stubborn hydraulic fitting on my log splitter. The 2.1" inner diameter seated perfectly, and the 50 durometer rubber sealed it tight on the first try.

Michael T. ★★★★★

The 50 durometer gave just enough flexibility to seat these o-rings into a tight groove without tearing. Used them to rebuild an old hydraulic cylinder and they held pressure perfectly after the first test.

Owen M. ★★★★★

The 50-count pack is perfect for stocking up, and the 50-durometer hardness makes them pliable enough to seat easily without tools. Installed a few in a hydraulic fitting yesterday and they sealed up tight on the first try, no leaks at all.
