Hazel ★★★★★

I needed a reliable seal for a hydraulic cylinder at work, and these AS568-237 o-rings with a 3.359" ID fit perfectly and held up well at 250°F. The 50 durometer material feels just right for the application—firm but not too stiff.

Elizabeth E. ★★★★★

The 50 durometer compound on these o-rings is noticeably more forgiving than the harder ones I've used before, making installation a breeze without any leaks. They fit the groove perfectly on my pneumatic cylinders, and the 70-pack gives me plenty of spares for future repairs.

Lucy ★★★★★

These seal up perfectly on my hydraulic fittings, and the 50 durometer softness makes them a breeze to seat without any tools. Having 70 in the pack means I've got spares for every project I can think of, and they've held up fine in the cold shop so far.
