Elizabeth ★★★★★

I needed a reliable seal for a pneumatic cylinder rebuild, and these 70-durometer X-Rings seated perfectly without any leaks. The 1.984" ID was spot on for my application, and they handled the 150 psi test with no issues.

Christopher Z. ★★★★★

These are the second set I've ordered, and the 70 durometer hardness makes them feel solid without being brittle. They're a standard AS568-226 size, so they dropped right into my existing grooves without any fuss. Good value for a hundred and twenty-five pieces.

Aurora B. ★★★★★

The X-ring profile gives a better seal than standard rounds, and the 70 durometer handles the -40°F range without getting brittle like some cheaper nitrile I've tried. These fit perfectly in my hydraulic fittings and the 125 count means I won't be ordering again for a long while.
