Customer Reviews (4.4 / 5 · 5 reviews)

Claire ★★★★★

Installed these on a large hydraulic cylinder, and the 70 durometer gives just enough flexibility without being too squishy. They slid right into the groove and haven't leaked a drop after a week of use.

John W. ★★★★★

Fit my application perfectly right out of the package—the 11.734" inner diameter matched my flange exactly, no wrestling needed. These are 70 durometer so they're firm enough to seat well but still give a solid seal when compressed.

Madison U. ★★★★★

The 0.139-inch cross-section feels nicely thick and durable, and the 70 durometer hardness works great as a replacement gasket seal on my compressor tank.
