Alexander ★★★★★

I’ve been through a few packs of these for a rebuild project, and the 70 durometer hardness feels just right—firm but easy to seat without tearing. They handled a steam line sitting around 200°F all week without any swelling or leaks. The 150 count per pack means I won’t be reordering for a while, w

James V. ★★★★★

These fit perfectly into the AS568-159 slot I needed to replace. The 150-count package gives me plenty of spares for future maintenance.

Abigail D. ★★★★★

Installed a few of these AS568-159 o-rings in a hydraulic fitting and they seated perfectly without any leaks. The 70 durometer feels plenty firm for the pressure I'm running.
